King Arms 15rnd CO2 Magazine for M1/M2 Carbine GBB

If you're running an M1 or M2 Carbine from King Arms and want better cold-weather performance, the King Arms 15rnd CO2 Magazine for M1/M2 Carbine GBB is the key! Made with a steel shell and alloy/polymer internals, this magazine holds 15 BBs, loaded through the feed lips on top. The CO2 compartment is accessible through the baseplate, requiring 12g CO2 Bulbs to function. The main advantage of CO2 is its near immunity from pressure variation in colder weather, but it also provides incredible recoil and cyclic speed. Just make sure you stay on top of maintenance!
