The CMMG 22lr AR conversion kit has been available for several years to rapidly change the caliber of a AR 15 rifle or M4 Carbine from 5.56 to .22lr caliber. The kit has evolved over the years from 22ARC, BRAVO and ECHO versions, each version adding new features and modifications. The BRAVO version kit can be upgraded to ECHO features by buying the CMMG charging handle and forward assist adapter parts which are offered separately.
This video covers the installation steps of the BRAVO and ECHO kits and recommendations from the manufacturer for best functional results.

I just purchased this CMMG Bravo .22LR Conversion Kit today. I should receive it in about a week. Once I receive it, I will take it to the range and post the results via my YouTube channel. Great video. Very informative. I just subbed to your channel. Keep up the good work my friend.
