Description.
Every serious air gun shooter knows – one mag is never enough. The STI Combat Master Air Pistol Magazine (4.5mm CO2, 20 Rounds) is your go-to spare for the legendary STI Combat Master, and it does more than just hold BBs. Whether you're working on your tactical reloads or just want uninterrupted target shooting time, having this extra mag on deck keeps the momentum flowing. Its snug fit and reliable CO2 delivery system mean you’ll spend more time firing and less time fiddling.
With a capacity of 20 steel BBs and powered by standard 12g CO2 cartridges, this mag ensures consistent velocity and satisfying blowback action. Built by ASG, a respected name in the airgun world, the magazine is engineered to withstand repeated use—be it on the range or during rapid-fire drills. The finish is matte black to match the Combat Master’s aggressive styling, creating that seamless aesthetic purists and collectors appreciate.
If you’re training for speed reloads or simply hate the pause between shots, investing in an extra mag like this is a no-brainer. For anyone who owns the 4.5mm STI Combat Master CO2 airsoft gun, this is the exact mag you need—no wobbles, no compatibility headaches. And here’s a tip for fellow skirmishers: carrying two or more of these can mean the difference between staying in the fight or fumbling for BBs while your opponents close in.
