Expert Answer

Answered by Hunter, Gear Expert, from OH, United States, on April 05, 2022

This CMMG, Inc 22LR AR Conversion Kit, is designed for the CMMG Mk57 5.7x28mm upper receiver groups. So it will not work with a 300 Blackout upper.

Will it work with a bushmaster .223 upper

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on February 01, 2022

No. The CMMG, Inc 22LR AR Conversion Kit is for converting 5.7x28mm to 22LR on CMMG 5.7 conversion uppers only. It will not work with .223/5.56 chambered rifles or the CMMG MK57 lower.

will this work with a 5.56 NATO upper

Answered by Dustcommander100, member, from SC, United States, on July 19, 2021

Per the CMMG website, the Mk57 works with the 5.7X28MM Conversion upper receiver only - not the 5.56 or .223 chambered rifles. For all the details, check out the info at CMMG.com. The info is a bit cryptic and takes time to understand.

so you need a different charging handle or do you need to buy a different charging handle

Expert Answer

Answered by Brandon B, Gear Expert, from IL, United States, on August 11, 2021

Just remove the existing CMMG bolt carrier group from your 5.7x28 upper and replace it with the drop-in conversion. Pair the upper with any Mil-Spec AR15/Mk4 lower receiver and then use the included magazine to safely shoot .
