Wow. Michael, I can’t even begin to thank you enough for your superb, informative videos and meticulous testing. I’ve learned a ton from your vids. The fact that you created an enlarged model with PVC tubing and wooden pole to demonstrate gas block bleed off made me say to myself, “Now here’s a guy who really loves what he does.” THANK YOU THANK YOU, MICHAEL!

I could build a damn house from start to finish with you explaining it to me.

I was always confused by the instructions SA includes with these. But your explanation makes perfect sense and now I understand how to use these. So back to the range I go to dial in my rifle!

Good video I liked it. One issue that nobody mentioned either on the video or comments. The cyclic rate between the control and bleed off. This is huge. The bleed off SIGNIFICANTLY lowers the cyclic rate and that is critical for suppressed and full auto weapons. It also tells you that the bleed off is working far better than indicated in the video as the gas in the restricted flow is increasing the cyclic rate and pushing the gun harder...from what I can see at least 10 percent. With the bleed off there the cyclic rate for suppressed and unsuppressed would likely be similar. This is big just for that but also there is likely no need to change the gas setting when you plunk a can on there. I have been using a heavy-azzed MicroMoa gas block just for that reason. This is probably a better (lighter) solution...at least for me.

Wow! Thanks for taking the time to build a mock-up to show how the system works. Unbelievably helpful

I've watched a number of your videos, and they are all excellent. I have a brand new, adjustable gas block from another company sitting in my parts box. However, I watch this video everytime I get ready to do a build and decide that I just have to order another one of these or my build just won't be up to snuff. Superlative should ask to host your vids about this product. I'm not sure why they go to the trouble to make such a unique device and then completely fail to explain the advantages in using it. I've looked at numerous videos about this item, many don't even touch on the bleed off feature. Your production is by far the best on the subject. The pipe and dowel setup that you made is an excellent visual aid.

You should do these videos for mfrs or vendors. Very informative. Thank you Sir!

I use these gb on my 556 guns and soon to be my 308 build. Excellent illustration of the bleed off mode, I have to explain this to customers at the range fairly often.

Great job explaining this system. You made it very easy to understand. Thanks.

Outstanding video! Very clear and well thought out commentary. I’ve dove into multiple videos of yours after this one. New subscriber!

I really like your attention to detail, especially on the 2nd part to this SA gas block video. I have this exact gas block for a Aero 308 build. 18 inch barrel, rifle length gas system. I appreciate the time and effort you put in your videos. thank you. I am subscribed now, btw. Keep up the good work.

WOW! What a GREAT vid!!! Your detailed explanation of not only the install but actual function of the gas block has me totally sold and will be on my order for my 308 build. Your calm demeanor makes your videos easy to follow. As it happens, my first build has the older version of this gas block and was extremely satisfactory, so I've got total confidence now. THANKS!!!

Excellent tutorial. You spoke slowly and used great visual aids. Thanks!

Excellent video Michael! Your demonstration with the PVC pipe cleared up so many questions I had about this gas block. Keep it up

Your explanation of this adjustable gas block was spot on. I particularly enjoyed your model of how the system works. Great job!

I love that model - told me everything I was wondering immediately when i saw it. Nice job!

Incredibly helpful and informative! Really, great job! Subscribed

I bought one and was kinda confused with the purpose of the bleeding of vs restriction. Now I'm very impressed, thank you.

Great video! I can't see how you don't have more subscribers. Love the attention to detail and examples. You sold me on this for my Aero M5 build. Thanks for taking the time to do this!

Thanks for this man. My Superlative Arms AGB just came in the mail today, I installed it, but now I was really unsure how to adjust it. You cleared everything up very well. Thanks again, man.

Excellent video! You answered all of my concerns on this gas block and it’s operation. Thank you👍👍

Great review Dr Bell. Thank you!

Great informational video. This definitely gave me the push I needed to buy this gas block. SA should be thanking you.

I enjoy the fact ur vids are always factual and I guess I would call it a scientific and objective approach to ur videos . Keep them coming!! Thanks Darin Kleen

This was very helpful. Thank you!

Thanks for the video. Very clear explanation appreciate the time you put into it.

Fantastic breakdown

Great video and demonstration of the SA gas block, they should be paying you for this video!

Great insight into this product! Thank you!!!

Great video - very informative. I have a .300 BLK 10.5" pistol that is way over-gassed. This is the perfect solution.

The enlarged model saved my sanity. I couldn’t figure out why I couldn’t get my rifle to cycle properly. I had it “wide open” which was causing too much bleed off. Which I assume caused insufficient pressure. Time to rebuild the rifle a 3rd time. It pays to understand the products ur using!!!

This video helped me decide whether this was the right purchase for me, THANKS!!!

You touched on all the points good Sir. Most excellent.

This information is gold. I was having all manner of function issues (ftf, fte) with a new rifle that has the SA adjustable gas block. Thanks to your videos, I now understand how the gas block works and … more importantly … a process to adjust the bleed off. It was horribly overgassed, putting way too much energy into the BCG. 30 minutes later, the rifle now runs like a sewing machine; just enough gas to function but not too much.

Brilliant prop for explaining how it works. Thank you I'll be replacing my SLR that seized up and doesn't run right after getting the screw un-stuck

Can’t thank you enough for this great explanation. I left the range a few days ago scratching my head over this gas block because i couldn’t get the gas dialed in. Shame on me because I didn’t read the instructions before setting off to adjust it. I just assumed it worked like every other AGB and the bleed off just happened in conjunction. Then when I couldn’t figure out why I couldn’t get the system adjusted and did read the instructions, I didn’t t really understand the bleed off concept. Now that I’ve watched your video everything I saw at the range all makes sense. Going to now watch your follow in video to see if you show how to adjust it. Thank you for a very informative video. I haven’t found a video this helpful in a looong time.

great video and explanation. the makeshift model was a great aid for me visually. good stuff!!!

Best explanation on adjustable gas blocks!

Great video! Excellent demonstration

Still the best video around explaining a ajustable gas block

Great model. I have two of these and they make a lot more sense now

Outstanding informative information. 🐢🇺🇸🐢🇺🇸🐢🇺🇸

Very informative video, thank you

Thank you for explanation, Michael

Good info. I have been wondering about getting this gas block.

Great explanation, thanks a million!

Awesomeness. Great video. I know its a late comment but just found it. Keep up the gr8 work.

I did not know why the instructions said to continue turning ccw once at the max gas (4.5 turns out). Great video I know understand how the gas block works. I was restricting the gas and not actually letting it bleed off. Great explanation thank you!

Very well done sir. Thank you.

Michael, this is a fantastic video. Thank you for really good thorough information! I want to talk to you about every gun question I have! Lol Really great content sir!

Great explanation!! Very helpful

Very informational Thankyou

I'm a very visual person and while your camera work and lighting isn't the best, your explanations and mock up visual more than make up for it!!! I learned a lot from your video and greatly appreciate you sharing your knowledge and expertise!! Well done!!!!!

Great Vid!!!

Your video helped me justify the extra cost of this product.

thank you, I learned quite a bit.

That barrel looks awesome.

That is one wicked looking barrel Mike

The reviews the manufacturers *shoulda* done! Thanks!

That was very helpful

Very helpful....thank you

Btw….Luth ar has an adjustable gas block for $17!!! From the reviews I’ve read, the “detent screw is in the back of block facing shooter, and is extremely hard to adjust with any fore rail. But, the price discrepancy makes me believe it’s complete crap! But, I have a “extra” 16” upper that I’m building for long range….i will be running it suppressed (ocl polonium) 99% of the time. I believe I’ll throw $18 to luth ar to see how it goes. Adjust it with rail off and keep it that way. Maybe find a sweet spot between canned and uncanned

Superlative arms adjustable .625 gas block is working very well on my 16" ar.

Thanks for this video, it came with no instructions at all.

I know this video was 3 years old but damn was it just what i was looking for! I wonder how well that gas block has held up over 3 years??

Your like the Tom silva, norm Abram from this old house, except for guns. I like it.

Another great one Michael.

Wow. This is some of the best in depth research I’ve seen on KZfaq. So with a 16 inch mid length un suppressed would you recommend to use the restrictive settings or the bleed off settings with this gas block on a DI 556 ar

Awesome.

Great video man! I have a ar10 243. So if I back mine out all the way I'll be at full bleed off right? I'm using a supressor. My thinking is to back it out all the way an start turning it in till I can eject 3 o'clock an lock back on one bullet. Basically the exact opposite of using the restricted part of the block.

Thank you for all that you do! My question is….what’s the value of a “clamp on”? In my particular case…I want to add it on to a manufacturer built rifle (iwi Zion 15) and I’ve noticed my existing block is the set screw style, meaning it’s most likely pre dimpled for the block. In which cases would a person prefer the clamp on (besides a non dimpled barrel…wouldn’t you want to use the set screw and just mark and dimple your barrel? Seems like the best way to confirm gas hole alignment.

i love mine and have beat the crap out of it 👊 still goin strong

Great videos Mike! I just completed a 300 black out upper with the set screw version of this gas block. The installation instructions that came with this gas block say "Carefully slide the gas block towards the shoulder, allowing for a .025 gap (use feeler gauges) between the shoulder of the barrel and the back of the block. This will locate the gas hole in the barrel with the gas hole in the block." I noticed you pushed yours all the way up to the shoulder, and have had no problems. I also pushed mine to the shoulder, but haven't test fired it yet. Do you have any feedback on this? Thanks, keep up the good videos!

Thank you so much for explaining how it works. The instructions while yes it tells you what to do but for someone new to a bleed off block, I so hate to admit it but it had me scratching my head. Iiterature is so contradicting, states “patented bleed off system, bleeds instead of restricts” in a nutshell. But yet states turn counter clockwise 4.5 turns to “fully open” maximum gas pressure... then at first I misread and thought you’d naturally turn clockwise to decrease gas and counter clockwise to increase. Which from here yes clockwise would decrease because it restricts gas, however counter from there also decreases .... now I understand this is where bleed off starts... so in essence it does act as a conventional restricting gas block up to 4.5 turns out and then bleeds off thereafter fully open.... Haha I feel like an idiot but seeing your video before my first time out with it really would’ve saved me a lot of headache! They should state that inside 4.5 turns is restriction and outside 4.5 turns is where bleed off starts. That alone would explain a lot. Either that or I am an idiot but bleed off gas blocks being brand new to me I had no idea how it worked.. Thank you again for clearing this up! 2 years later and still helping people understand!

just subscribe to your network.....I do my field testing by brain logic, and now with your videos I can save myself from some heavyweight migraines. I am reviewing ALL your videos/ they are fantastic..... thank your for your time.. I am trying to accomplish the same results as a adj. block but with buffer weights and springs (giving gasses time to exit) using the dwell distance and muzzle exit distance from block ( using mid. and rifle gas ports) as the main factor... QUESTION: do you think I'm wasting my time.. ...all black rifles matter..

Excellent video! I just bought one of these gas blocks and it came with zero instructions. I went to their website and there are no instructions there either. I'm baffled why they'd make such an awesome device and then not support it one bit. This was extremely helpful. Thank you! I too wondered about increased perceived sound with a can. I didn't think to wonder about bullet velocity, but I was wondering if there would be any flash from the vent.

It's almost scary watching your vids. I'd swear you can hear me talking to you. You some how answer all my questions as i ask them.

Great review, also you used the wrench to tighten the barrel nut, I have the same handguard and the with on the 1 1/4" nut won't fit any wrench's I have, they run on a taper towards the inner part of the wrench, at the end of the wrench it's .457 and towards the inside it's .578, the width just a little ways up the jaws. Where did you get the one you used with your socket ratchet ? Looks like I can even make one on my mill from 3/8" flat stock. Well done video, 👍👍👍👍👍👍 Thanks so much Michael

Hi, great videos, would you say it’s worth installing this on 11.5 inch sbr which will always be used with a suppressor. Brand is Daniel Defence ddm4- 7s.

Great informative video! I was curious if you could give me a little more info on the handguard? I just purchased this gas block and am having trouble finding a handguard that has enough clearance. All of the UTG Pro ones I've looked at dont seem to have enough room

Recently I read a thing in TFB about a Socom profile barrel that the Army had patented that was finned very similar to the GM barrel you are using.

You did a great job explaining this! Can you post a link to the continuation of this build? Thank you in advance!

regarding the slide lock charging handle. i had one on my .308 build and nearly every shot the handle would cycle back when firing and after maybe 35 rounds the charging handle broke. mega replaced it fast but I do not plan on ever using it again

Good to Finally hear someone in the gun world say the word ambidextrous correctly.

In the video you say you can run the block in restrictive mode if you choose to. While that is true, just FYI, I just talked with Superlative yesterday because I had some questions and they informed me that the block is designed to always be run in bleed off. The only reason the restrictive part is there is for the option to completely close off the gas if needed or wanted. Just thought I'd pass the info along.

What did you torque your clamp bolts to?

Awesome video. I have this and a snach charging handle and still get domed with a decent amount of gas. My system also fails to completely cycle sometimes. Would allowing more gas allieviate both of these issues?

How does this clamp on do as far as being a secure attachment method to the barrel??? Meaning have you had any problems with it walking, rotating, or coming lose is some way? Im looking for a good adjustable gas block for a 6.5 Grendel Proof Research barrel that I'm building a rifle around and I've never used a clamp on before I always dimple my barrel for set screws... Great video just subbed...

I just stumbled upon your site, and I have to say, you have a real gift for clearly teaching and demonstrating. I'm new to the AR world, and I want to upgrade my Ruger AR-556 and an incoming S&W MP10. What is the bar that you placed the upper receiver in to do your build? The piece that is held by your vice? I'm sure that is a dumb question, but I'm shopping for tools for the AR platform, and I notice that there are multiple ways to secure the upper receiver for working on it. Seems like AR-15 and AR-10 tools and builds are really interchangeable?? Thanks in advance.

Also, roller cam pin vs forward controls design np3 coated mil-spec cam pin?

Did you make the video with this in the field, im curious about the DI, with the suppressor on and off, i was hoping to be able to find one setting where the rifle would function with or without the suppressor in it

On the hearing test. Which test point did you use for test , front left of gun or at shooters ear? I know what industry standard is , military is said to have moved tk shooters ear.

Great video, but i actually I have another question for you. Their website says "the gas adjustment screw does not restrict the gas flow; therefore there is no erosion or seizing of the screw". Did they change the design because in this video the screw does restrict the gas flow for the first 4.5 turns. I emailed them but I'm not sure if they'll reply. Thanks!

I really enjoy your in-depth video reviews. Add another person to your "subscribed" list! How would you compare the Superlative Arms Direct Impingement Bleed-off Adjustable Gas Block to the Superlative Arms Piston Conversion kit for anyone looking to build a highly reliable custom AR-15? Are either products something that you would trust to install on a rifle that you might need to bet your life upon (my particular usage is home/self defense)?

I’ve been thinking about getting this gas block for my current 6.5 creedmoor build. I’ve never tried a clamp on style block. I’m not sure if it would hold as well as the normal set screw type, but I wouldn’t mind not having to drill dimples in my carbon fiber barrel. Since you wouldn’t need to use a jig to make the dimples how far forward or how far forward would you place the gas block to make sure it is line with the gas port on the barrel?

Thanks for great vids, question, dimple or clamp gas blocks whats the real lo down?

Hey Mike, I just got my Superlative Arms Piston Kit in (thanks to your videos!) and it doesn't fit under the hand guard I was going to use! Can you tell me if it looks like it will fit under the UTG Pro hand guard you used in this video. I'd really appreciate it. Thanks! Keep it up!

Can you make the necessary adjustments with a rail system / MLOK hand guard installed, or do you have to tune it, then install the hand guards?

I know it’s an old video but I have a question. I’m building 10.5 308 pistol and will be using with a van when it clears but until then I’m gonna use it without. Is this gas block good for that?

Just saw a video where the guy says that the bleed off gas block has a loud pop sound when fired so to use a suppressor with these types of gas blocks is defeating the purpose. Is this true? So is the choice a quieter rifle with more gas in the face or a not so quiet rifle with less gas in the face?
