That was a Brass Fact tier intro. 5min of explaining the prelude to the video I'm so proud.

That clip of Brock getting smacked by a spent casing in the face is never going to get old.

Imagine if Hop found the perfect handguard but it was only in Keymod.

6:06 here's a brass fact, it ejects from the right side of the rifle.

People thought the Stag Arms Spectrum rifle was the true autism rifle, then you build this masterpiece.

Hop is like an ex-redditor that hates reddit but continues to make content that people used to go to redddit for. Props.

19:47 is where the video actually starts if anyone is interested

Mad scientist Hop is my favorite Hop. Edit: The fact that cynical Hop has a cat, and optimistic Brass has a dog is just....pottery.

This is a dissipator. It dissipates things.

“Eminently slappable face” Lololol, a true gem of phrase

I'm glad RifleSpeed is starting to get more recognition. Easily one of the most convenient AGBs on the market. A little pricy, but totally worth it

I doubt you'll see this but one apparently hidden benefit of the adjustable gas block is that you can train on malfunctions and switch back to a working rifle quickly

As engineer on a lunch break, thank you for pissing me off specifically :)

Watching Hop go fully autismatic on niche AR features with Brock-style background lore is incredibly soothing. We're reaching peak KZfaq.

"slappable face" is an actual prerequisite to signing up on reddit.

5:47 is the most swag psuedo-retro-GWOT hipster build I've ever seen.

This adjustable Gas block is probably the answer to the 12.5" Barrel gas system problem

Nice, Grüsse aus Deutschland, Heilbronn, schön Flecktarn, Wald Holz zusehen, Forest Wood.

I installed one of these on my mid length gassed 16" custom build and this Completely turned it into EVERYTHING I Ever Dreamed of! I run a T-2buffer and I am on setting 6 it is Purrrrrrfect!

Appreciate the content. Having plenty of rifles that are good to go including builds and off-racks, it’s nice to see someone constantly testing new innovation products which takes a lot of time. - Way more entertaining for gun nerds than the paid reviews of complete guns.

On my wedding night to get the mood set I’m playing your videos hop.

Dude! I am an engineer. I loved your rant about gas issues and cold! You went into a deep dive into the insanity of the AR. There is an alternate way to reduce the gas, a gas tube with a smaller hole. The nice thing about the AR platform is the lack of training needed to be a gunsmith. There is one issue with the AR, that is the frustration finding parts that will work for your build.

You made a good choice. That handguard looks really good on that setup!

I really want to try one of these builds... Might get around to it sometime, the Riflespeed block is definitely a cool product. Thanks again for the content!

Man this is giving me some really great ideas. This honestly seems like a really great style of build especially for shorties. Like, shorties with carbine length systems are what they are. They aren't horrible, but definitely not what you really want these days given what we and the military now know about what the most reliable and functional gas lengths are.

Looking good.

Too tired to even threaten me with violence huh? I felt that one. 😂😂😂

Solid build. FocusTripp put together a "dissipator" a while back with interesting results, dude does some great work! "Stay Strong, Chase Excellence Brothers." - Godspeed

That’s a lot of dissipation

Have a midwest industries quad on my 16”’carbine. Love it, stiff not to heavy and no screwing with adapters and crap contacting my barrel and such. Just stick it on and done. They dehorn/deburr it too so unlike the KAC quad I had in Iraq, it doesn’t chew up your clothes and hands.

I really appreciate the dedication to all things Dissipator, and hadn't thought about the riflespeed setup. Thanks Hop!

Brother, looking at KAK items right now, interesting timing. That said, the rifle length gas system Dissipators really stay nice and low... Good job!

Ya, the Riflespeed gas block is pretty sweet, but getting a hand guard to work can be a real struggle. It sits taller the normal low pro blocks, so not all handguards will slip over it. And if it does, make sure there is enough room that the barrel stays free floating during firing.

Definitely the best reviews on Dissapator and 16" with rifle length gas. Hoping to see a long term/round count update on this rifle.

I made a 16in rifle gas build similar to yours with a KAK Industry barrel, lo pro standard gas block, and a A2 stock with standard rifle buffer parts and haven't had any issues with it cycling with or without a suppressor with 5.56 ammo. No gas to the face and it runs stupid smooth. I have a LaRue MBT2S trigger in it and its very nice to shoot.

Hop, the RS system is solid. I have 3, all on large frame gas guns and they been flawless over thousands of rounds at matches

Love the vid, I enjoy these build type videos. I am currently working on a 20” AR-RPK upper that has been in my mind for two years now. Going to use this this gas block, with a DD mlok handguard, and a 20” criterion HBAR. I want it to be accurate and absorb heat well. No joke about their barrels never being in stock, mine is on back order.

7:23 not unjustified, adjustables are known to seize from carbon alone, i snapped a tool inside a slr gas block once

I got the same kak barrel and went with a centurion two peace quad rail handguard. Now my other 16" rifle length gas barrel I got an FN 18" had my gunsmith open up the gas port, cut and thread the barrel to 16" and attached the rest of the hardware to include triangle handguard. I used the H&R upper and lower receivers from PSA. It's my favorite AR to use for pretty much everything now.

I went with a rifle speed system based off your video. Awesome gas block. Went on my 308 noveske 16” barrel with a 14.5 zev handguard. Runs flawlessly.

That zero recoil setup is hilarious. Id get into competition shooting just to justify a build like that with an aluminum bcg lol.

Literally just watched both your SFAR videos this morning. Drove couple hours and this was at the top of the feed when I opened KZfaq again

So glad you got one of these. Been running one on a suppressed 300 BLK for awhile and it’s just fun. Only issue I’ve had is freezing up the plunger due to the pistol length gas system. Lubing it up once a while takes care of that issue. From 300 supers to subs to with or without suppressor it fits my build perfectly.

I AM an engineer and didn’t get pissed 😂. For someone who’s not an engineer, ya definitely explain things in enough easy enough to follow detail that you should definitely be one in this industry broham 🤙🤙

I have 2 uppers I've installed the Riflespeed adjustable gas block. Absolutely awesome toolless adjustable system. The last thing you want to do is rummage around for an Allen wrench or even a shell case to adjust your gas. Just grab the numbered sleeve and click it up or down a click to tweak your setting. And perfect ejection pattern.

BF catching that piece of brass in the mug was hilarious. At least it didn't go down his shirt, lol.

Thanks Hop great info!!

After Focustripps video I became motivated to make this myself. I havent started putting the list together but I know for sure what its gonna be "called" Mk12 Mod D. The PRI tubes come in 14" and I think that would be a sick rifle concept

I shall refer to all my AK shorties as combloc dissipators.

I built a 16" rifle gas competition gun with a Criterion Hybrid barrel and I've been super happy with the results. I'm running an empty buffer and a Geissele Super 42 spring with a AIM lightweight bolt. I'm not even sure the Riflespeed was even a thing a couple of years go when I built the gun so I used the SLR and setup the gun to run on a fairly hot .223 load when dirty.

Great to see another Hop video so quickly. FYI for any SCAR owners, the Scarburetor is a similar setup for that platform. @eduardo moniet

I have a 11.5" midlength faxon which is definitely in the dissipator category. I use fixed gas on it because like hop i dont like adj gas blocks. While I am sure it recoils more than a tuned gun would, with an H3 and sprinco red it still has considerably less recoil than my 10.5" carbine gas gun, and it will still work with cheap .223 reman loads. In fact it has never failed to function in any way, in temps from about 0f well into the high 90s. Also, hello Hop.

I've got the standard collar Riflespeed gas block on a Roscoe K9 11.5'' barrel with patrol gas length and a BCM MCMR10 and I can report that it is hella flush (with the help of a belt sander).

Been wanting to try out one of these. A new dissy build seems like a great way to put it to use.

Fantastic video!!! Haven't seen much on the Tube of Yous about the AR10 version of the Rifle Speed system.

Glad you make these videos.

Awesome video. Thank you! 🤙🪖👮🙏🇺🇲

This a sick setup. Great content!

Good video. Informative. Thanks.

Honestly I don't mind a longer vid. You put out good stuff man

Of all your builds, I think this may be my favorite

It makes me appreciate my piston rifles. You have a supressed and non supressed setting. That's it. That is all.

We can only hope that someday our content is half as good as yours man! Love the video as always.

The last 30 seconds was worth the re-watch.

Im gonna use this video as inspiration to finally finish my 10.5 300BA hog gun. Thanks hop!

I've had one of these on a shorty .300 blk I built for a bit over a year at this point. I was really impressed, my goal was to make a super light gun that works reliably both suppressed and unsupressed, I was very close to accomplishing this. With super sonic .300blk it works great both suppressed and unsuppressed, with subsonics though it has occasional hickups when unsupressed.

Cool build!

Very interesting, good info, thanks

Another great review Hop.

The best explanation on dwell time and the Rifle Speed adj gas block.. Finally, someone got it right..

Great review!!👍🏼🤙🏽

I made my own 12.5 mid gas barrel by cutting down a PSA freedom 16 inch barrel. Sizing the gas port was the most tedious part. It is an absolute joy to shoot.

I like the preamble!

Can confirm, 12.5 mid with 10.5 and shortest riflespeed gas block collat configuration is excellent.

One of your best videos man

Hop, i feel compelled to chime in here and remind you that ALG V3X rails are back in stock!

I love these build vids

I'm Running a POF Adjustable Gas Block on A 18" 1 in 12" twist Barrel, and it Also Had The Problem of Being WAY Over Gassed ( along with the JP Silent Buffer / Recoil System ) @ first I Was Running The Standard Gas System And It Felt Like The Rifle Was Going to Brake in Half. Now It's As Smooth as Can Be. I'm Still Sorry about hearing You're James's brother.

Have several rifles with gas adjustability. Piston dissi also. All valid point made. set screws need sets screws😂

The riflespeed gas block makes the AR essentially a infinitely adjustable system like the FAL. I loved the one I had on a 300 BO 7" upper. A simple twist to go from supers/subs/suppressed/unsuppressed...sorry for the boating accident.

I used the rainier 16" dissy barrel, a2 front post and a brt tube. A2 rifle stock and buffer and even with a turbo t2 its still a good shooter.

a 20 min hop video? nice

Thanks hop 🤙🏽

That's pretty neat.👍

Interesting concept I might try it with a kak complete upper and aero adjustable gas block.

Hop, your videos could never be too long.

Feels good knowing I have that Criterion!

I literally just randomly picked the anderson A4 dissipator video... and then saw this drop! I went to look for the upgrades videos and this dropped! Its like you read my mind through the internet. I tried to think of how... nearest I can tell the 5G waves were reading my thoughts that were amplified by the antenna created between my skull and the the toilet bowl. The pushing energy and yelling sent this message back in time to give you the idea for the video! This means there should be an A-Team and Baywatch reboot any minute! Woot!

I have a 16" Criterion hybrid rifle gas barrel with a fixed block and a brt tube. Running an A5H3, thing is incredible suppressed. I have to go down to an A5H0 unsuppressed, but it still cycles fine dirty and in shitty weather.

I have a 8.5" .300 Blk with the Riflespeed. I really like it.

I used to build uppers for an armory with the aero (ba) pencil barrels pistol lengths, Usually 10.5 with carbine length gas systems, they all ran really well. I used one w the t2 buffer and it was still pretty punchy plenty of gas. Unintentional dissipation lol.

Spinta Precision also makes (made?) a 16" Rifle gas barrel. Or at least did years ago when I built my dissy.

Oh damn, was wondering who was doing that when I saw it on insta. Awesome to see this. Thinking I am throwing the hux on my 12.5 mid.

I never thought I’d ever hear Hop say “hella flush”

3:15 Why charging handle... WHY?? 6:10 BOOM! IN DA FACE!!! 19:47 Murder Mittens! **I'm not going to touch the 'if you are cold, they are cold' Revisit that with condensation in mind**

I keep thinking I want a KAK dissipator barrel but haven't capitalized on it yet. I want an A2 front sight gas block. Would be super sweet if it was adjustable. Great video as always

Excellent content

thanks.. informative

I'll have to build one of these for sure
