Hello all, RON L here - SERE SURPLUS
I have used Metalform mags for over 20 years now and I've yet to have any function issues with them! I've as well Tried Winson ED Brown and others witnthe same Results but Piad way too much more (In My Opinion for the Wilsons) than I did wit the MMC, Ed Brown or Metalform! Looks like quite a few mags ae Simply Name Items and others just perform? LOL I prefer drop flooplate mags and the ones I have are MMC and worked quite for for over 15 years now! I've tried the Checkmate USGI mags and if I get for a Good $ they are well worth the search as well!
