Expected more from Aero

MEH. The bolt catch was visibly bent. Contacted Aero, they requested pictures (which I sent) and haven't heard anything else. Safety was also very gritty, so swapped that out with another (PSA) safety that I had laying around and it feels much better.

Aero is the sweet spot


As far as I am concerned Aero Precision provides the perfect balance between cost and quality. I have used 7 of these kits now and have yet to be anything other than impressed. The fit and finish is excellent and the tolerances are perfect. When Aero is in stock, there is no reason to look elsewhere. You are either going to spend more for identical quality is you are going to spend less for lower quality.

It’ll do.

Everything was pretty good quality. When i went to test fire the trigger was malfunctioning. Other than that its a good start for the assemble your lower.
