The CMMG upper didn't used to actuate the bolt hold open. You had to get an add on kit and use special magazines.

I don't know if that is still the case or not.

Fishbed77 probably knows for sure.

Personally, I went with the M&P 22-15.

I have one set up as close as possible to my Colt 6920, I have the other setup as a lightweight tree rat rifle.

Significantly lighter than both of my other tree rat eradicators a Marlin 39a and a Marlin 881.
