Cmmg Magazines: 22LR Firearm Conversion with 3 Magazines

Whether you’re dialing in training drills or stretching out a budget-conscious range day, converting a 5.56/.223 AR-pattern rifle to rimfire is one of the smartest moves a shooter can make. It reduces wear on your centerfire ammunition supply, lowers recoil for marksmanship practice, and lets you log quality trigger time without emptying the wallet.

Design and compatibility

CMMG’s approach with the 22BA651 is straightforward: make the conversion as user-friendly and reliable as possible. The unit is intended to be swapped into an AR-platform rifle in place of the bolt carrier group. Because it’s a drop-in style conversion, experienced shooters will appreciate the minimal tools and time required to switch between 5.56/.223 and .22LR. The brand CMMG has built credibility in conversion systems and components, and this kit continues that emphasis on practical engineering.

Magazine and feeding considerations

This kit ships with three 25-round magazines. That supply lets you run multiple full magazines during a session and troubleshoot feeding without hunting for spare mags. The 25rd capacity is a balance between bulk and function for rimfire conversions; it gives more continuous fire than small caps while keeping cycles predictable.

Ammo, hammer, and function tips

Function reliability with rimfire conversions comes down to small details. The product notes recommend a round-style hammer; notched hammers can introduce cycling and ignition problems with .22LR. For best performance, the manufacturer specifically points to 36 grain plated nose bullets as the most reliable choice. That’s useful guidance: certain bullet profiles and weights will feed and chamber more consistently than others, especially in semi-auto conversions. If you’re building a training plan around this kit, plan to test a couple of 36-grain brands to identify the one that runs best in your rifle.

Range applications and training value

Using a .22LR conversion like the CMMG 22BA651 keeps recoil and noise lower, which helps new shooters and experienced marksmen focus on fundamentals—trigger control, sight picture, and follow-through—without the distraction of centerfire recoil. For instructors or coaches, a conversion is a way to simulate drills more affordably; for duty or preparedness shooters it’s an efficient way to practice transitions, reloads, and malfunction drills with lower operating cost.

Installation and maintenance pointers

Installation is plain: remove your rifle’s bolt carrier group, insert the CMMG unit, and ensure magazines seat properly. Because rimfire runs dirty relative to centerfire, plan shorter cleaning intervals and keep an eye on the barrel and feed ramp for lead and carbon build-up. Routine maintenance—field-strip, brush, and lightly oil—will maintain reliable function across sessions.

Reliability troubleshooting

If you experience failures to feed or extract, first verify you’re using the recommended round-style hammer and 36-grain plated nose ammo. Next, confirm magazine seating and check the magazines for worn springs or feed lip deformation. Cycling problems are often traceable to the small differences between rimfire and centerfire ammo profiles; methodical testing of ammo and components will isolate the issue.
