great lower


For the price this is a great lower and matches great with a aero precision upper. I build custom complete uppers and lowers and you can not ask for anything better.

Almost the best I have seen


I gave it a 4 out 5 because the pivot pin plunger hole is IMHO out of spec by .030, even though Aero states that you have to use an Aero LPK to get a flush fit pivot pin. Finish was good, nice flair on the magwell and I liked the 60* markings, even though I use a 45* selector. Cons are you really need to use an AERO M5 upper or your build will look bad. I suggest using a standard CMMG LPK and buy the pivot pins and bolt release from Aero's site.

I would never ever hesitate to buy from PA.


I have been wanting to start another project, time came when the lower was on sale, couldn't pass up the price, plus the great services from Primary arms. It was a win, win for me. Flawless lower as expected from these guys. I have purchased from them many times, they have my business as long as I can shoot a firearm. Thank you for your great services PA.

Hess Upgrade


Lower was purchased to upgrade a Hess AR10 to allow for modern AR10 magazines, feed reliability, and ease of use. The lower fit very well to the Hess upper with only slight modifications to the upper to accommodate modern 308 magazines. Worked like a charm.

Good lower for the price.


Nice finish. Match perfectly with DPMS upper.Can use AR15 lower parts except the pivot/take down pins, bolt catch and magazine release.

Aero stripped Lower


Pretty sexy... Just waiting on an upper.Some nice features, and excellent finish.

great service


Shipped quickly and product is in perfect condition.

Very Helplful


Spoke with a representative over the phone and he was very helpful in assisting me throughout my purchase process. I was able to get the lower I wanted and when I wanted it. Thanks so much.

Great Choice For Me At An Awesome Price


The Aero Precision lower worked great for my LR .308 build. Anodizing was nice. The price was fantastic!!My FFL told me that none of his distributors could touch the cost. That's even after his $30.00 for the transfer.And as always, Primary Arms "customer service" is topshelf!!!

Aero Precision stripped M5 lower


The lower is very well and finish are perfect. It aligned exactly with my DPMS upper. All lower parts were very easy to install especially because they provide a threaded pin instead of a roll pin for installation of the bolt release.
