Excellent quality receiver and shipped fast. Big fan of primary arms great prices and super fast shipping. I will be back.

Top notch


The quality of the upper is superior, and primary arms was one of the best place to deal with, great shipping speed and well taken care of. Will definately be buying from here again.

Upper reciever


Good quality comes in a nice display box and I received it fast. What else could you ask for ?

You can't really ask for any better when it comes to forged, flat-top upper receivers. Both casting and machining are top notch and it fits perfect on all four various manufacture's lowers. Compared to an Anderson forged upper I recently received, the Aero has a better fitment to the lowers tested with, the bore for the barrel extension is a nice tight fight where the Anderson was a bit looser. The Anderson had a little casting issue. I would, without a doubt, buy this again.

Good upper


I installed this upper on a Anderson lower and installed a Radical f/a 16" barrel with a seekens/primary 15" hand guard on it. Perfect finish everything fit nicely during assembly.

Love AP!

Fits great onto an anderson lower. I really like the way it looks and definitely want another one.

Super customer sevice from P.A.

Aero Precision components are first rate, this was no surprise.

Primary Arms customer service is second to none - I ordered this Sat. AM and it was in my mailbox on Monday AM. Great job by P.A. and by USPS!

Not quite precision upper

by -

The big issue I have with the upper I received was it appeared to be milled a couple degrees off. This would probably be ok if it was a blem or something but not a brand new QC’d product. I figured I would reach out to aero precision to ask if this was within their tolerances for this product, it’s been a month and I haven’t heard back. So minus a star for the defect and minus one for their non responsiveness. Primary arms delivered quick as usual, I’ll doubt I’ll order AP products again.

Fast shipping. Perfect fit.

Not sure how free shipping is as I paid for mine since I needed it early. Processed and shipped same day. Exactly as described, works with all my lowers. Will buy again!
