Can't beat it for the price


Fit was good finish was quite matte and would have been better with a little sheen to it but for $50 it's hard to complain. Nice sized closed trigger guard.

A bit of a hassle


Don't know why but the last one of these receivers I worked with was not threaded for the grip screw. I had the correct tap on hand so it was only a minor inconvenience .

Nice lower


Ordered the lower at the end of the day on Friday and even with Labor Day being on Monday I picked up the lower yesterday. Super fast shipping and everything fits like a glove. Thank you and I will use primary arms for most of my ar purchases.

Worked well


Closed ear means closed trigger guard. This was my first build and it took me a while to figure that out and I bought a trigger guard. Oh well. I also had quite a bit of trouble tapping the first pin in. That could've been the parts kit or user error though.

Great buy


I purchased 2 of these not long ago and I was very please with Primary Arms quick shipping and the product was perfect. Stowed these away for a possible future build. The finish and machining was great. You won't be disappointed with these lowers.

No problems


I matched this up with an Aero upper and Aero parts kit. I had no issues on the build. Nice finish on it also

Best per dollar.

Grabbed one of these, as the price was very good.
The lower I received was way beyond the dollars I spent. Fit and finish were excellent.

Absolutely the Best!


Best price, fast shipping. Primary arms is by far the the best place to shop for Firearm parts and accessories!

Good stripped lower

I installed a cmmg lower parts kit into this lower with no problems. For the price I am​ gonna eventually buy a few more of these for future builds.

A Great Price For 1st Build

by -

The fit and finish seem to be good. I am in the process of ny 1st build and there have been no problems. (other than launching springs and detent into orbit.) shipping was quick considering the paperwork involved and dealing with FFL. I would have bought more it my budget manager, wife, would have alloted funds, LOL
