Agree. "P Mags have a great rep, but 30 years of metal mags is a hard habit to break. Only consistent jams I ever had was with Israeli plastic mags in a AR 180. Switched to aluminum, problem was gone. Not to discredit them in AK's they work great, and P Mags passed the Iraqi and Afghanistan sandbox test. I just like a good metal mag, and Armalites are excellent.
