Great kit for a PCC build


Parts were of great quality as to be expected from aero. Plug and play solution for a ar9.

Works Well With FM Upper..

Using this setup with an Aero lower and a Foxtrot Mike 9mm complete upper. So far working well with no short-stroke issues using 123grain 9mm reloads. Quality is on point.

Great Kit

Easy kit to get everything you need for the butt end of your EPC9. I did change out the spring for a JP spring just because I like those springs much better then Mil-spec. I did have to shave a little off the rubber part of the buffer to get LRBHO to engage.
