I bought this on sale for a .308 build. Used a bear creek arsenal 18 inch barrel, and aero lower parts kit with JP trigger job. Only problem I had was with a Monstrum .308 15 inch hand guard barrel but. After several emails back and forth and 2 different barrel nuta sent to me from Monstrum, I still had to have a gun Smith modify the barrelbut, because it was too thick and prevented the gas line from going into the upper receuver. This is an awesome product for the price. I plan on buying more. Dont hesitate. Get this combo! I actually have this 5 stars, but internet messed up.

Know what youre getting....

The one I received had a major blemish around the safety engravings on the lower. Big scratch in the finish. Makes me wonder how it will hold up once it actually sees the elements...
<br>
<br>The fit is good, but hard to give a decent rating when its a blemished part that never should have shipped unless discounted.

Very good fit and finish. Assembled with DPMS, Strike Industries upper and lower parts, 3lb drop in trigger, KNS anti rotation pins, Magpul furniture, 24" 6.5 Creedmoor barrel. No issues on build and when on sale this upper lower set is a no brainier.

Awesome price and service

I hate Primary Arms. Their constant sale and low price (such as this) is taking funds away from other fun activities. As to previous post about high dpms rail, I bought .308 17” handguard. Perfect fit and height...just got lucky or other handguard is not spec?

Mine isn't a true DPMS high pattern.

by -

Nice set, but it will not work with all rails. I bought the appropriate Diamondhead free float handguard, and it's a hair too tall. For that, I had to take two stars off.

Impressive Quality

by -

I pretty much echo everything that has been written so far, I would just like to add that when you pin these two receivers together, there is virtually no slop between them, the two units become one.

Excellent deal when on sale, one issue

by -

This set is seriously a steal when on sale. However, Armalite .308 aluminum magazines do NOT fit. You're probably better off using the polymer magazines.

A STEAL, ESPECIALLY AT SALE PRICE

by -

I can't believe how great a deal I got on this set. Worked perfectly with DPMS .308 lower parts kit, except pins (not needed, it came with them) and fit/finish is as good as could possibly be, at any price.

Worth every penny

by -

Great set defenetly worth the money, it’s solid.

For the Price, this is a solid receiver set, but be prepared to do a little work

by -

For the price, this is a solid receiver set, if it wasn't for the price, would have gave it 4 Stars. It is DPMS High Profile. Didn’t use a DPMS Lower Parts Kit, purchased 6/32 NC x 3/16 set screw and purchased Aero Precision Threaded Roll Pin, filed about 1/8 inch off the end.
<br>
<br>Purchase a 6/32 NC Tap and clean the threads for the Bolt Catch and the Rear Detent Threads. Bought 3 of these sets, had to clean the threads to get the screws to go in smoothly.
<br>
<br>The Aero M5 Rail doesn’t fit on this upper receiver due to the Thickness of the Material where the Port Door Rod Hing. The M5 Rail has “wings” on the sides of the rail that cover over the Upper Receiver past the barrel Nut. I was hell bent on making it work, so I modified the Upper Receiver to fit. Once it was finished, looked like factory, rail covers over the machined area. Used Aluminum Oxide to restore finish where excessive material was removed.

Great for the money

I bought this set on Black Friday special. I paired it with a Wilson Combat 16” 338 federal barrel, aero lower parts kit, aero ejection port cover, aero forward assist, aero buffer tube kit, and a toolcraft BCG. With this combo I was able to shoot .71 moa at 100 yards. The only hiccup I had was the bolt catch pin would not thread as far in as I would have liked. The pin was larger than the receiver’s hole. I took some sandpaper and sanded the pin and it fits perfectly. Just picked up another to build a 308.

A DPMS Hybrid style upper, forged 7075-T6, for an insane value.

by -

This is a kind of hybrid receiver set. It employs a DPMS high pattern top rail, overall dimensions, and barrel extension....BUT the rear "cut" of the upper and lower is the Armalite pattern. It basically means that you're not gonna be able to swap another upper onto your lower. That being said, I am VERY pleased. Trigger pin holes are in-spec and work perfectly with my Geissle SSA-E. The handguard pin hole dimple worked perfectly with my MEGA/Zev WedgeLock handguard. And the receiver raceway for the BCG is true as well. Unbeatable for the price UNLESS you want to use one lower with multiple uppers (which is much more difficult to do with AR10's due to gas system and buffer mass tuning).

ringing gongs at 800

great set. no issues at all with the build. but that's to be expected from matrix. top notch company

Amazing quality

Got this set when it was on sale and couldn’t be happier. This was my first lr308 build so I hit a few hiccups with wrong parts, but PA took them back:) Overall If buy another in a heartbeat and build a pistol with it...... my wife would kill me though;) Great product, and great customer service!

Unbeatable price

The receiver set is flawless and was cheap as heck!! The set includes pins, takes pmags, and a dpms high handguard. I used it to build a 20” distance gun and was very happy with fitment and quality. If you are wantzing to try a 308 build after building 223/556 this is for you:) Word of advice though...... but the proper vice blocks.

Nice AR-308 set

by -

Bought this on black friday for a nice price. I put it together with a DPMS 308 lower parts kit and everything fit fine. It does come with it's own pivot and take down pin. The barrel nut is also DPMS. My only complaint would be that this seems like a combination of armalite and DPMS standards (you won't be able to use a different DPMS upper on this lower as the profile is different) but if used as a set as sold, you shouldn't have any problems. Primary Arms delivered to my FFL very quickly.

Great Receiver Set at an Unbeatable Price

Great matched receiver set made here in NH by the same company that makes the receivers for Ruger's SR762. Great fit and finish--accepts all DPMS High parts
