$2000 worth of gauges and tools. Uses two quarters to check a gas key clearance. Finally, a gauge I actually have! This is why I'm a fan. 👍 Always learning something new.

Had no idea that the gas key could impact the extension end of the receiver. Never thought about that.

Like how this did better than a few of the high end lowers you’ve looked over

I learn new stuff from every video. The more you know, the more you realize how much you don't know.

Love my Anderson lower with my palmetto state armory upper. Shoots very accurate 👌

This is fantastically educational, I don't even have any problems with my ARs and it's fascinating to see how you inspect and unpack these very important details.

I feel like you've done this once or twice.

I've been building and working with AR's for a few years now and I still learn so much from your videos. Would love to take a class sometime.

That slave pin for installation of the trigger is a awesome idea !!! Thank you for the tip !

I'd love to see you do a physical on an Aero M4E1 lower.

Lol, i love when ar snobs bash on "the poors" for Anderson lowers. Its just a box to put stuff in. If you put good stuff in the box, it works great. I think Anderson had some QC issues, but they seem to have improved.

I've had nothing but praise for Anderson lowers. The several I own are excellent. As always, Thanks for the video!!

Hammer drop lock tool is awesome. I just went to go see if my buffer tube had a gas key markings.....all good. Thanks for the great information.

I have gleaned some great nuggets of information and tricks of the trade, thanks for sharing your knowledge.

Was suggested in a fb group to check your vids out and I’m hooked… fairly new to firearms and just watching your vids on the insides of these firearms especially cuz I have an Anderson has really given me confidence to not be afraid of disassembling my rifle and learning more about em, thank you!!

Thank you for another lesson. Your efforts on our behalf are appreciated.

i know this is an old video, but thank you so much for all the informational content you put out. Your video with the rear takedown pin trick saved me so much hassle, and i went through my lower as you went through this one in the video just to make sure mine was exactly the same results as yours! Thank you so much for being so informative and down to earth!

Thank you for sharing your knowledge in these videos. You are doing folks a real service.

Thanks, This video helped me out, I just got a Anderson lower and it seems to check out as well. But then again I used a different parts kit then the Anderson one.

Saving this to watch later.

10:42 stops video and gets AR

Thanks for using the quarters. It helps with folks that may not have the gauges.

Always learning from your videos thanks.

Outstanding work you do here! Very educational👍 thank you for your worl

Thank you for sharing your knowledge and another great video. I don't know why some try to knock Anderson manufacturing. I have never had an issue with them. Like yourself, I mic the trigger pocket walls on every lower prior to building, and Andersons have been dead even every time.

Been waiting for the Anderson lower video!

My god, this videos is going to break the internet...

Kentucky represent. I've been telling y'all!

Any chance you can make a video on how you stake a castle nut the Colt way?

I have a brand new Anderson upper and where the upper meet the lower you can see the edge of the upper has a slight “wave” to it. Doesn’t bother anything except my ocd.

Most bestest informational AR-15 vids on KZfaq! Thank you for your efforts SOTAR!

Great content man!!!!! You got a new subscriber. 👍

I didn't know any of these tools existed, or things to check were actually things to check! man that was a impressive work bench! I have my mallet and a allen key

Heck yeah Bro. Great video. Wish everyone would see to these details. Carry on👍

I’ll be honest, I didn’t expect it to do that well, but I was pleasantly surprised considering the price point of that lower.

I love these videos. I'm in the process of creating a SOTAR dictionary. So far I have: Egged-out Clocked Three-Bore

Please review LWRC. Fantastic channel

Damn that is some gorgeous staking

Built a grendel off an Anderson and enjoy it. Best value in a lower IMHO.

Someone has surely caught it by now, but that mark on the receiver from the gas key is likely from the operator placing an upper on the lower without the buffer and spring by accident and charging the bcg to the rear. Seen that all the time in the army, when soldiers turn in their weapons after cleaning, and forget the buffer. Great video.

Great vid, thanks!

There are Anderson haters out there, but having been a 2111 in the Marine Corps, I see nothing wrong with the ones I have used in the civilian market. The ones I’ve had come across my bench have all been well made examples. Semper Fidelis🇺🇸

Now I need more tools...Brownell's magazine catch tool. Oh wait I don't have any of his gauges (but do have go and no-go gauges). Also watching these videos is like watching "Casablana", you know what's going to happen next and how it's going to end but you always get something different out of it every time.

If the buffer goes too far to the back and strikes the gas key and lower receiver a quick fix would be to add quarters at the back inside of the buffer tube before putting in the spring until you have the correct clearance of the gas key to receiver, it’s not a permanent fix but can get you out of a damaging jam!😉

awesome - thank you!

Actually looking to build my first AR. Been looking at Anderson's on a few other videos. think you pushed me off the fence. Great job/video

Great video good sir. An 8-pound Mil trigger must feel like dragging a dead cow across a 4-lane highway. I would suggest he pick-up a LaRue Tactical MBT-2S, or MBT-2S-SB either of which is a 2-stage National Match which break clean at 3-to 3-1/2 pounds. They are on sale at this time for $80 for the hammer/trigger set with springs.

I've had my pins walk out (daniel defense parts kit) on my anderson lower, I assumed either one or the other was slightly out of spec. Installed some anti rotating pins as my hillbilly fix. I spent more $ on the lpk than I did on the lower.

What a great channel. Why am I just seeing this ?

Anderson is a very good value brand. The only issue I've ever experienced is a very tight tolerance on the pivot pin holes.

Good info here. I have to check some things on my AR’s now.

I bought some 80% Anderson lowers a while back. First thing I noticed was the rear lug recess (presized and anodized ) on one of them was undersized. I haven’t checked all of them yet.

A true Guru AR 15s very impressive I use a wood block that I made for my trigger drop test

All lowers are not the same.. that being said an in spec Anderson is gonna run with the best..

Been waiting for this one for a bit. Good post.

good video thank you sir.

Great job!

This channel is going to grow big time.

Anderson lowers are the best bang for the buck. I prefer the Aero Precision parts because of the adjustment screw to match up to the upper, but the Anderson lowers are extremely well made. They have their manufacturing process well dialed in.

Video may be 3 years old, but as a horseman in real life, I always like to see a grass-fueled pony get through a checkup and be declared healthy. As a shooter, that goes just as true for the gunpowder fueled "Poverty Ponies" - Got a small herd of those along with the hayburners. Never have understood the grumbling about Anderson lowers. No blatantly obvious problems with any of mine so far. 👍 Nice presentation.

Can you do some other lowers BCM Aero thanks for all you do on the USE TUBE

You would have a field day with some of the parts I have had that are out of spec.I have bad luck..I have a question that u may only know.I ordered 3 dsarms m16 cut lowers in the last couple weeks. I built one and originally installed a cmmg parts kit and noticed the fcg pins fit awful one side will stick out while the other side is sunk in, (not too crazy) I noticed that if the selector lever was 1/4 off of safe and I pressed the trigger hard it drops the hammer, I ordered a larue mbt 2s trigger for it and it will not install,i can get the pin to go in one side but on the other side the hole on the receiver is too low for the pin to go thru lol .i tried the trigger on the other 2 dsarms lowers and same thing, I tried it on my colts and every other lower I have and it fit easily. I ended up putting a alg act in the dsarms lower and switched out the safety, detent and spring for a dpms that I had and the hammer still drops when the safety is barely disengaged off safe...is this normal for m16 cut lowers? I noticed on the dsa that there’s more space from the back of the trigger piece that sits below the groove in the safety

My staking DOES NOT look like that hahaha! Love your videos.

Great video. After watching your video, I looked at my lower receiver and noticed that my buffer tube is slightly off. Clocked just a slight amount off, not bent or anything like that. I thought to adjust it, but its only slightly off and doesn't seem to actually matter functional speaking or otherwise. I can't really see why it being off slightly matters. How closely aligned does it have to be? It seems if it is off a little it wouldn't actually matter. Am I wrong? What would be within limits? I served in the Army, I wouldn't be surprised to find a few military rifles slightly off in that regard. Especially considering the way some of the dopes I served with handle things...

Hello, Thank you for using an Anderson lower receiver for this video. Was that a forged or billet lower? How many rounds has that receiver seen?

Man oh man they way you just popped them trigger housing pins in like it was nothing makes me hate myself it took me a long time maybe a hour and a half to get mine installed but for my own defense this was the vary first AR I put together. I also have a stripped Anderson lower.

Thisnis the one i have been waiting for. These are the cheapest lowers, cant wait to see if it is a GO or NOGO.

Bought an anderson lower once, and only once. Something with the safety detent hole was out of spec, as in the safety would barely engage. When the selector was moved to safe, it would barley engage. Just the slightest bump and the safety would switch to fire. Replaced spring, detent pin, same issue. Sent the lower back to anderson, second one had same issue. Ended up trading that lower off.

Anderson provides the lowers for many high priced rifles. Anderson knows what they're doing and has been doing it for a long time. The price is not indicative of the quality. People will always pay for the most expensive things for the wrong reasons.

Curious if you have done any checks on Odin Works Zulu 2.0 adjustable butt-stock? It has an additional, small spring in their receiver extension. I have one on my AR15 and it works great. It changed the felt recoil just enough to go from good to very good target reacquiring after firing and my ejection is about 3:30-4:00. I rechecked the BCG space as you had in this video just to make sure. Thanks!

Yes bro about time you do this one I would love if you could do one on MIDWAY USA complete upper

So far I say Anderson offers a good product for the money. As for any brand It is good to run a proper sized drill bit with your fingers in the roll pin holes to make sure the hard coat didn`t tighten up the holes and you will have no issue driving the roll pins in. Cudos to the School of the American Rifle.

You should do a Aero Precision Gen 2 lower.

What tool was used to stake the castle nut?

Let the fuds who say Anderson lowers are out of spec watch this video

An odd phenomenon is when the hammer pin in slightly pushed in an not fully seated the gun becomes full auto. That would be a good video explanation

What is your profession opinion of the Anderson upper and lower 🤔. I used one in one of my builds and was very pleased with them. Fit and finish was nice with the 20 year old lower Delton parts set I found in some of my tucked away parts, lol

The impact mark on the lower receiver could be from the back of a 22lr bolt carrier.

I got rid of my Anderson lowers I bought three at one time two of them would not except aftermarket magazines. One had a safety dent hole. It wasn’t drilled deep enough.

Poverty Pony FTW! :) And if anybody thinks I'm being snotty at Anderson lowers, think again - I'm a happy owner of 3 of 'em. Only problem I've had with any of them turned out not to be a problem with the lower, but the takedown pin that came with the LPK - it was just a titch fat, so it took some extra "oomph" to get it to either seat, or pop out. Not enough to put the rifle out of action, but enough to be annoying when trying to open or close it. Chucking up the pin in my drill-press, spinning it up to 540 or so and touching it lightly with emery cloth a few times cured that problem.

*JUST* *AS* *GOOD*

So I take it you’re not a fan of grip screws with a set screw to take slack out of trigger? Interested to hear your thoughts.

do you have the spec's info that you show us in the video's to were we can get a copy of them.

❤ this

Ive assembled 3 Ar-15’s with Anderson lowers and I had clearence problems with all of them. I needed to dremel out the mag release button openings and the bolt release openings, plus they have a sloppy fit to the uppers. Other than that they are totally usable and work as good as my 2a and Aero receivers. For my budget builds I now use ATI forged lowers because its threaded to capture the rear take down pin detent spring and they have the threaded hole for the teflon tipped lower to upper tensioning screws. The ATI’s are cheaper where I live, and Ive had no problems with clearencing to install lower parts kits. And I use only quality lower parts kits.

One of my Anderson lowers was initially super tight to attach the upper to, but seems to have broken in a bit. Even now the carrier appears to rub on the top of the buffer tube inside. Haven't noticed any serious issues with this yet, and it is a pistol made with all cheap parts. Is there anything I should look to do to it or have checked up? It's already run fine with 200 rounds or so.

I wish my G2S trigger install went that easily...

Some of these other gun experts on You Tube have extra skill where they can evaluate these receivers and BCGs without needing any of these fancy gauges. They can just hold it up and look at it with their naked eye, and be like umhm yeah that is a great BCG, everything looks perfect or whatever. No gauges needed for these super pros, their eyeballs just know.

I have a clone complete URG-I upper with the DD m12 gas block.It isn't pinned just dimpled,screwed and marked with paint.Would it be worth it to pin it also?

Impact mark on the back of the receiver looks like someone closed the upper on top of the lower without the BCG being fully seated in the upper. Looks more like a scrape than an impact mark from the gas key?

I just want to know where I can get some of these tools.

I've built about 10 AR's, two with Anderson Lowers, and the Anderson's have functioned flawlessly. Can you spend 2x more on a lower? Yeah, but why?

Hey, I have one of those! Felt like a good budget option at the time. Sadly I don't have an upper on it yet. Soon ™

Those black plastic grid pattern things you have your screwdriver bits in are interesting. Where did you come by those?

When are you going to do another Run of the gauges?

I have a P.O.F renegade+ and when I break it down the rear takedown pin is so tight that I have to use a hammer and punch, any ideas to remedy this? Takes a lot of effort and im afraid of damaging the rifle.

How would one send in like a BCG to get inspected?

I have an Anderson lower that I purchased as a complete assembled lower, however I do not know where the parts kit came from. The reset works flawlessly when the trigger is released quickly, but it drops the hammer every single time it’s released slowly. Any ideas? I figure I’ll replace the entire FCG.

Haters think it's at 1.5 speed, but it's actually at 0.75 speed so we mortals can process what Chad is doing.

hey SOAR what are your thoughts on forged vs billet lowers for average shooters. honestly i dont think unless your job requires you to carry one, the forged vs Billet is not a huge argument. we should all keep in mind with these type of discussions most of the AR15's in America sit in safes or closets and it makes zero difference.
