The CMMG .22 LR 25-round magazine is designed for CMMG rimfire conversion kits that let you run .22 LR through your AR-15 platform. This is an open box sale, offering inspected magazines at a reduced rate.
Open box means the packaging has been opened or removed, but the magazine itself has been checked by our staff. These units offer the same function as new-in-package magazines for shooters who prioritize value over sealed retail packaging.
The 25-round capacity gives you more trigger time between reloads during training sessions or plinking. It works with CMMG’s dedicated .22 uppers and conversion bolt carrier groups that drop into standard AR-15 lower receivers.

What Open Box Means for Magazines
An open box magazine has left its original packaging but remains functional. Western Sport inspects each unit before it goes on the sales floor. You get the same feed reliability without paying for pristine retail packaging.
For high-volume shooters who go through multiple magazines in a range session, open box pricing stretches your budget. The magazine body, follower, and spring do the same work whether the box was opened or not.
Compatibility with CMMG .22 LR Conversions
CMMG .22 LR magazines are built specifically for CMMG conversion systems. If you’re running a CMMG dedicated .22 upper or a .22 conversion bolt in your AR-15, this magazine is designed to fit that setup.
Rimfire conversions let you train with cheaper .22 ammo while keeping the manual of arms identical to your centerfire rifle. The magazine inserts into a standard AR-15 magwell, and the bolt carrier handles extraction and feeding.
If you’re using a different brand’s conversion kit, call 817-393-4000 to confirm compatibility before ordering. Rimfire magazine patterns are not universal across all conversion systems.
Why 25 Rounds for Rimfire Training
A 25-round magazine balances capacity with reliability. Rimfire ammunition is less consistent than centerfire rounds, and magazine springs under extreme compression can sometimes cause feed issues in any brand of rimfire magazine.
The mid-capacity design also keeps the magazine from extending too far below the magwell, which matters if you shoot from a bench or rest. You get plenty of rounds for most drills without the bulk of a 50-round drum.
