EMG Magazine for BLU & GLOCK Series Gas Airsoft Pistols (Model: Basic / CO2 / 25rds)

"This is based on the CO2 magazines. The mags work very well however the threads on the caps MUST be aligned correctly as you can strip them very easily which would make them useless. These mags' seals are very reliable as I used a single cartridge for a entire day. (Used in 4 pistol matches, reloading bbs between rotations.) I prefer the 1911 co2 designs as you can less likely strip the cap but it does work as long you carefully and make sure the caps threads are aligned. If you pick up the co2 versions I would recommend to practice a couple of times screwing on the cap without a cartridge. Again MAKE absolutely sure the threads are aligned before attempting to elbow greasing it! (A single twist when misaligned will ruin the threads trust me I speak this from experience.)

"The mag itself is surdy and feels great, however the threading for the cap Stripped on two of the co2 mags i ordered and now are pretty much useless.

"My basic co2 mag came in and the second I put a co2 canister it started to leak hopefully I just got a defective one and they are not all like that
