  • For ASG STI Combat Master
  • 24rnd Capacity

For those of you who have been hunting for STI Combat Master magazines, here they finally are! This magazine is a replacement original magazine which holds 24 rounds and a 12g unthreaded CO2 cartridge within the shell.

Full description


The magazine can be loaded with BBs using a speed loader, either through the feed lips or the port on the front when the feed spring has been pulled down. To load the CO2, simply lift the feed spring follower near the base of the magazine, allowing the polymer baseplate to slide off to the front. This reveals the CO2 reservoir. Simply unscrew the plug, insert your cartridge, and tighten the plug back down, replacing the baseplate once the plug is fully tightened.

Those looking to fill their pouches up and light up the enemy with their Tactical Master, your prayers have been answered!
