Hey everyone,
My bolt is not catching properly, when its an empty magazine. My build is a Aero M5 lower, and 18 inch upper with an aero BCG. . The gun cycles fine, but won't lock back on an empty mag. I can lock it back fine manually with no problems. I took a picture of the measurements of the spring, buffer, and the buffer tube. I read somewhere that it might be the screw that holds on the stock on that sometimes they can effect how far back the buffer can go?
Anyone have any ideas?
Thank you.
