Converting an AR15 to .22LR, CMMG Conversion Kit Range Report

CMMG .22 LR Conversion Kits at the Range

Steve and Caleb from Brownells head to a cold and windy Big Springs Range to shoot the CMMG .22 LR setups featured in Caleb’s earlier video.

The previous walkthrough covered conversion kits and dedicated rimfire uppers. This time, the focus is on shooting steel and enjoying some affordable plinking.

First Shots on Steel

The session starts with a run across the plate targets. Hits connect, but some plates are reluctant to fall. Steve and Caleb note that the targets appear to be set up for centerfire ammunition, making them less responsive to the rimfire hits.

It is a casual shooting demonstration rather than a measured accuracy or reliability test.

Affordable Rimfire Fun

Between strings, Steve and Caleb discuss how little ammunition each run uses. The lower cost of .22 LR is a major part of the appeal, making repeated practice and recreational shooting easier on the ammunition budget.

Both hosts quickly decide that another run is in order.

Trying the Compact Setup

They switch to the compact dedicated .22 LR setup and take turns clearing the plates. Both enjoy its handling, with Steve describing it as handy and Caleb saying he needs to shoot it more often.

The range session puts the earlier component discussion into context: these setups provide an enjoyable way to spend more time shooting rimfire.

Conversion Kit Convenience

Steve and Caleb close by highlighting the conversion kit’s appeal for owners of compatible AR-15s. It provides a rimfire option without requiring a separate firearm, while preserving the ability to return to the original centerfire configuration.

For the differences between that approach and a dedicated .22 LR upper, see Caleb’s earlier overview. For this outing, their verdict is straightforward: both setups make for a fun afternoon on the range.
