"Very unimpressed. Very hard to load to capacity. When fully loaded (20 rounds) it vomits the first 3-4 shells in the magazine out if you insert it into the magwell with the bolt open which indicates weak feed lips. The polymer feedlips are reinforced, but it appears to be either aluminum or a soft steel and does absolutly no good. These work O.K. if you only load 15 rounds, but I bought a 20 round magazine so I expect it to function as such. Do not waste your money on these promag crapsicles. Maybe HK will make a 15 or 20 rounder for the USC some day, until then use the factory 10 rounders and change mags often."
