For: King Arms 50rd Colt M4A1 WA/G&P/King Arms GBB Rifle MagazineProduct Information:
i did not get mine from gi but these could be the worst magizine ive ever owned all of mine leaked and broke with in the first month or so i have 5 and all 5 have a leak or a broken feed lip or broken something. i would not recomend these even with a gun to my head i wouldnt waste the money on these ever again.
they hold 50 round... thats about all i got for a good thing ... and there made from medal. look nice
if you over fill or even put exactly 50 in it will break your bolt. all five of mine leaked. really heavy. terrible gas efficiency in anything below 85 but in 85 and up u might get a full mag... if your lucky. the gas loading nozzle is in a bad spot and is to small for most gas cans so you end up lossing more gas than goes in. i would also much rather perfer them have put it on the bottom not the back side of the mag. the little rubber gas directer thingy (couldnt think of the word) behind the feed lips breaks and gets chewed up by the bolt not a huge deal but not a good thing.
