Oh yeah. That reminds me now. For those that choose to go with the CMMG, it will work with your standard charging handle... BUT.. I highly recommend getting the dedicated CMMG charge handle to prevent any possibility of a spent shell jamming the bolt up. Not highly likely to happen, but if it does it's a bit of a PITA. (Ask me how I know...)......The charging handle
They have these for 180$ at Oregon rifle works. I only saw 2 left after I bought mine.I built a dedicated 22lr upper out of one of these:
Everything you need to convert your existing upper to a dedicated .22LR. Just purchase a magazine and you are ready to gcmmg.com
I use it on my SBR lower with a 22 suppressor. Really fun.
