ProMag COL22 10-Round AR-15 Magazine 223/5.56 Blued Steel Flush Fit

The ProMag COL22 delivers reliable feeding in a compact 10-round configuration that maintains the AR-15's sleek profile. This blued steel magazine meets capacity restrictions while providing the durability shooters expect from quality steel construction.

What Makes This Different

Unlike polymer alternatives, the COL22 features all-steel construction with a blued finish that resists corrosion and maintains dimensional stability under temperature extremes. The flush-fit design sits even with the magazine well, eliminating snag points during tactical reloads or bench shooting. Steel followers and springs ensure consistent cartridge presentation cycle after cycle.

Field performance demonstrates consistent feeding across various AR-15 configurations, from precision rifles to carbines. The steel construction maintains feed lip geometry under stress, while the flush design balances the rifle for offhand shooting positions. Competition shooters appreciate the reduced weight compared to extended magazines, and the compact profile works well for hunting applications where magazine length matters.
