some of the best mags made
These are some of the best mags ever made, but I have noticed a few small issues. They are coated in Teflon to resist corrosion, which is good, but they are very slick in wet or sweaty hands. The mag is very stiff to load because the spring is the same length as what is normally put in a 40rd mag(though this makes to reliable feeding). They also lack an auto sear travel cut which really only affects use in select fire AK type rifles. They also feed a little rough for the first 100rds or so. You can't tell it while shooting, but unloading by hand is hard until they're broken in. Still the best current production you can find!
