||This mag is SOLID.
I have had it for many matches and have dropped it SOOOOO many times (due to the different mag release on the m166 series). Dirt, wood, tile, concrete, blacktop, you name it, it's full metal structure has not cracked a bit!
-holds 2 mags worth (about 38rnds)
-Changeable bottom pieces
-follower does NOT lock down (you have to compress the spring by hand.)
-only 18-20rnds for a FULLY AUTOMATIC GUN?!?!?! (why is there no extended version yet?)
