Ratings & Reviews
1st Class Upper
by Peter -
First, let me say the shipping was absolutely stellar, so now to the good stuff, the fit & finish was first rate, Aero's "mil-spec" is IMHO better than my original upper, there is no slop, no gap between upper & stock lower (Aero lower in route) the hardest part of this build was installing ejection cover, really. You have to install it backwards, so to remove it, the handguard has to be removed, a small price to pay for an upper that's so well fit. all in all, I would highly recommend this anyone looking for a quality upper, well-done Aero Precision. Also, the box says T-marked but it's not. Not that big a deal as I know where my optics go.

This is a beautiful upper, well worth a few xtra $$$. Fde is spot on, and machined perfectly. Customer service is great, shipping speed is incredible, ordered Friday, delivered monday. Thank you
