Anderson Manufacturing AR-15 Stripped Lower Receiver

Great lowers. Never had a problem with any build. They sometimes fit tighter than the high dollar lowers I have. Now Dpms lower parts kits I've had problems with. Twice I've had out of spec selector switch's that would not fit. These lowers are great if you can deal with the my pony logo go buy one.

I have built over a dozen of ARs using the Anderson lowers, with Anderson and various other parts-standard, long range, & pistols. To date I have never had any problem with the Anderson parts.

I bought one of these last year, to start my first ar build. Slowly through out the year, I bought pieces for it. I finally finished my build the other day with a new upper. I couldn't for the life of me, get the upper to close enough to get the takedown pin pushed in. After an hour or so of cursing myself out for buying a cheap lower, stupid me discovers that I had the buffed tube screwed in 1 turn to many. I simply backed it out 1 turn and it closes like it's meant to now. Besides the logo on the side, I can't see a bit of difference between this, and my stag lowers. I will definitely be using these lowers for anymore mil-spec builds I do.

Used for Grendel build. Lapping tool proved face was true to bore in about 1 minute. Found exactly .001" clearance on barrel to receiver, so easy shimming with heat gun for tight fit. CMMG, Odin Works, Seekins, Geisele & Stoner parts all fit with no issues. Would definitely buy again.

Just got my lower transferred tonight, started to build it and ran in to immediate problems. The mag release button would not for the life of it, fit into its respective hole. After testing the button on my Stag lower which has some of the tightest tolerances I've ever seen, the button fit immediately which makes me think it was the Anderson lower and not my DPMS parts kit.
<br>
<br>I ended up having to belt sand the mag release button down a bit to get it to fit, which obviously ruined the finish on the release button and looks pretty bad. Now I have to hunt at my local shops for a button I can test on the spot to see if it fits because this silver button is irking me something fierce.
<br>
<br>The trigger guard, bolt release, and mag release were absolute nightmares to seat the pins but after that, everything went perfectly and with minimal fuss.
<br>
<br>I am not sure if I would buy this lower again after the frustration I experienced but the finish and fit into my upper were perfect.

I've had one for 5 years, with first a 20" then a 16" upper (Bushmaster and PSA, respectively). This lower has had thousand of round through it and been in a few action rifle competitions without any issues. No problems with GI mags, PMAGs or Hexmags.

It was flawless as I expected I will never again buy a lower from anyone else.

Bought 4 of these now and have been very impressed, and not only for the price. Anodizing is uniform on 3, one has a tiny pin hole underneath where the pistol grip goes, but overall great. Built 3, one still sitting in the safe, and had no issues with any. Fit perfect with my aero uppers, no play, normal amount of light pass through. Would 100% recommend for any build from entry level to mid/high end

Picked up one of these milspec Anderson lowers for a dedicated AR22 build and found it to be a great deal, with great fit and finish. I read several bad reviews so the first things I checked before building it were upper fit and standard mag fit, both passed with flying colors. Great deal on a well made and well finished product.
<br>The only thing that made this product better was how fast and professionally Primary Arms shipped it out; my FFL had it 3 days after I ordered it. Well done Anderson and Primary Arms!

I got three... two seemed to go together nicely and one appeared to have problems after assembly... could get the upper to fit onto the lower. After closer inspection, the buffer tub was extended to far and needed to be machined {filed} back to give proper clearance.

Picked up 2 Anderson lowers while on sale for my first AR build and I’m quite impressed. No blemishes (which I wouldn’t care) and very durable aluminum. Primary Arms made my in store pick up quick and easy. Was in the store for 10 minutes. I would recommend Anderson Arms and Primary Arms to everyone now. And the customer service was excellent!

AR lowers are meant to do 2 things, 3 if you count holding a buttstock.
<br>1. They hold the fire control group. If that area works as it should why pay for names or rolled logos?
<br>2. They are made to hold a magazine and to release it when the button is pushed. if it, the AR lower receiver does all of these things as they are supposed to do then paying more is simply a waste of money.
<br>Bottom line is this, buy ammunition and learn to make the second and 3rd and further rounds go into the same hole.
<br>The AR lower just holds the above. better triggers, better barrels and lastly sights open irons or scopes are what makes the shooter better.
<br>Buy these by the truckload if you can.
<br>One day they become extinct if certain groups get their way

Bought two Anderson lower receivers (sequential s#), installed parts kit other than Anderson, perfect fit. Used Anderson upper (installed BCA barrel in it) and other than Anderson built upper (PSA), both fit perfectly. Function, fit, and feed, no problems. Used several different brands of magazines and have not had any problem loading, feed, or drop. I would recommend Anderson products to any one wanting build an AR.

Bought two, on sale, separate households. Easy build. Perfect with two PSA rifle kits. Absolutely perfect. Everything fit without incident. My first lower build. Thanks YouTube. Absolutely fun.

Did not purchase a blem, but received a pretty bad blem. Bad finish and a good size hole in the metal on the outside of the mag well. But customer service as always was right there to help. Spend the little extra money on a spikes or an aero

built six ar 15 from anderson lowers and uppers never had a bit of trouble from them very good quality used some other brands back in the day [military time 30 +years ago] not so good a lot of fit work so save some money buy anderson from primary arms [the best ] quit complaining and build a top quality rifle

I bought 3 of these last year when there was a pretty good sale. Looking back, I should've bought 5 because that was the limit. So far I have used 2 in building an AR pistol and mid-length 16" rifle.
<br>
<br>I'm not an expert by any means, these were my first builds but everything lined up properly. For me, I decided that spending money on components such as a trigger was worth more to me than spending more on a "high end" receiver. Having read online about Anderson receivers potentially having issues with magazines, that was the first thing I checked. It lined up properly as did all the other pins and buffer tube. Very pleasant for my first build, I must say.
<br>
<br>I haven't had any issues and as if they go on sale again like last year, I will definitely pick a few more up. I waited months to build mine. It was a combination of learning through videos online and having the time to do it.

Say what you will about "poverty pony" lowers, but they work. I see no point in spending extra money for a different roll mark. I've used these lowers in several builds and they've always worked just fine.

Really nice lower it matches up with my upper very well. Wish I bought 2

I bought these on sale, assembled the first and fit and finish was perfect.
<br>Tried it with a couple different uppers and fit better than lowers that cost twice as much.
<br>Will buy again if I ever need another.

Anderson does have blem lower before buying the cheap cheap lower find out if they are blems
<br>I have built and sold thousands but not blem

I am a new customer with Primary Arms co. and I got to tell you, I have done business with other company but the level of care with Primary Arms so far is No.1., Customer care, quality of their product and prompt shipping, I mean, you place the order and before you know it is in your house ZAP!! in your hands, can't get any faster.. Thank you guys..

Awesome product. I brought 2, one for me and a friend and we built our AR-15 together. Works like a charm

When these are on sale at $30 or $40 you CAN NOT go wrong. I have built several for friends and these lowers work just fine. I have needed a small file here or there or even a bit of fine tuning BUT you are building a weapon from a stripped lower so get on with it. Want a perfect gun? There are plenty of ones pre-built on the market for thousands of dollars. I am a DIY builder so these are perfect. QWITURBITCHING and get on with your building!

All of these I have used have been fine.
<br>The trigger and hammer pins are not dependent on their fit in the lower for staying in and if one comes out, you have screwed up something during the installation.
