OK kit but not for Aero M5
Used this kit a couple of times with good results but when using on Aero M5 the mag catch is too short the front pin too tight, other have said the safety also doesn't fit right but I used a different item.
Wrong magazine catch
This is a 308 build kit but it came with the shorter ar15 magazine catch which i was able to make work but barely catches enough threads to hold.
CMMG LOWER
Found this kit to be of very poor quality. Pivot pin andtakedown pin did not fit Aero Precision M5 lower an safety selector needed rework to function properly. Initial price was good but new pins, rework time offset any advantage on price.
