Another top quality and great value airsoft magazine from Nuprol! This one is a metal cased STANAG style Mid-Cap magazine for M4 style airsoft rifles which has a capacity of 140 rounds but can be adjusted for MilSim use to hold only 30rnds.
The mag is made out of Alloy, with Polymer Internals and is a mid-cap design which is loaded from the top with the use of a speed loader meaning the pellets are released on a spring, so there is no noisy rattling or winding which can give your position away in battle.
