The ProMag COL22 gives you a solid 10-round option designed specifically for AR-15s that need a mag sitting completely flush with the magazine well. Built from heat-treated carbon steel with a blued finish, this magazine can take real-world use and won't rust on you when conditions get rough.
Inside, you've got a chrome-silicon wire spring and a molded polymer follower that work together to keep rounds feeding reliably through your rifle. The 10-round capacity and flush-fit design make this magazine particularly useful for bench rest shooting, prone position work, or anywhere else where a magazine poking out would get in the way. Some folks pick these up as spares when they're building out their magazine collection on a budget.
This mag is engineered to fit Colt-pattern AR-15 rifles and compatible platforms. The magazine locks in solidly and feeds both standard .223 Remington and 5.56 NATO ammunition without issues. The construction approach—stamped and welded heat-treated steel—is the same tried-and-true method ProMag has used across their product line for years.
The COL22 sits nearly completely flush with the bottom of the magazine well. This matters if you're using a shooting bag to stabilize your rifle or practicing prone positions where you need the lowest possible profile. Keep in mind that flush-fit magazines don't give you anything to grab onto when removing them in a hurry, which is something to think about before you buy.
Every ProMag magazine carries a lifetime warranty against manufacturer defects. It's made in the USA and backed by the company's commitment to keeping spare magazines affordable without completely cutting corners on materials.
Yes, the COL22 is designed for standard AR-15 and Colt-pattern AR-15 rifles. It will lock in and feed reliably. The flush-fit design means it sits almost completely flush with your magazine well, so make sure that's the fit you're actually looking for before purchasing.
Flush-fit magazines sit so close to the magazine well that they don't stick out at all. This is useful for prone shooting, bench rest setups, or anywhere a protruding magazine would interfere with your shooting position. The tradeoff is you won't have anything to grab onto when removing it quickly.
The COL22 is a solid option for range work, practice, and training. It's built from durable heat-treated steel and feeds reliably in most AR-15s. Like any aftermarket magazine, it's worth testing it thoroughly with your specific rifle before depending on it in high-stakes situations. The lifetime warranty means ProMag stands behind it against manufacturer defects.
Chrome-silicon wire is a premium spring material known for maintaining consistent tension and resisting fatigue over time. This means the magazine should feed reliably even after many cycles and extended storage. It's designed to avoid the spring weakening that happens with lower-quality materials.
