It's an upper
by Mully316 -
Decided to go with the slick side for an ultra-light build. I've always liked the fit and finish of the M4E1 Aero products, so it was a natural choice. This upper met my expectations. Finish was perfect and it fit tight with my ballistics advantage lower receiver. Solid upper from a solid company.
Aero Precision upper receiver
by Jeff-NH
I've purchased Aero Precision uppers / lowers to build 4-5 MSR's over the past few years. I built a .22LR rifle with a dedicated CMMG barrel and BCG with an Aero Precision M4E1 upper without the forward assist. Looks and Works beautifully. Aero Precision makes a great affordable product. Highly recommend.
Aero Quality, Primary Arms efficiency

This is my 3rd Aero purchased from Primary Arms. The Aero quality is consistent and the pricing is always exceptional from Primary Arms.
Aero always comes through

I’ve been building custom ARs for years and Aero is always my go-to for high quality, excellent fit and finish. Best balance of quality and cost on the market.
Works

It feels and looks great to not have a forward assist. Functions just fine. I am not one that thinks you need the best high end upper - I dont know the difference when shooting. It is solid. I would buy again no problem.
nice for lefties

great quality as always from this company
Ok Uppers
by Fred -
I mainly use these because they match the m4e1 lowers. my only complaint about these are that they are hit and miss for taking aftermarket dust covers. This one without the F/A worked with a Strike Industries enhanced one, but the CMMG 22lr BCG I had in it didnt. I have 2 other m4e1 uppers (with F/As) that a Strike Industries and a Magpul poly dust cover wouldn't work on.
Standard AeroPrecision

Quality upper receiver that matched perfectly with a lower receiver produced by a local FFL. AeroPrecision continues to provide quality parts without breaking the bank.
