Those 'new" madbull .28's are jamming in my pmags. Interestingly it they load only 65ish into the mag before the spring/follower gets stuck and the mag simply won't want any more bbs put into it. Occasionally the BB' will get caught about 1.5-2 cms from the top of the feed lips (again only with those madbull .28s). I've fully dissassembled all my pmags to clean and check the internals but I'm almost 100% positive it's these BBs.

The old style clear bagged madbull BB load and feed fine, as do KSC, Excel and BBBmax.

The PTS pmags are made from the same dupont polymer as the real pmags. Do a google search on those mags as well, They have had 5 ton trucks run them over, they have been shot, repeatedly thrown/dropped onto concrete surfaces. The material becomes brittle in cold but not at any temperature a typical airsofter will ever be gaming in.

The PTS pmags use a different ranger plate than the greenlines.
