Well sort of.
2nd hand CMMG .22lr AR15 upper. Not a slip in bolt conversion kit.
Has the 1 in 16" barrel, CMMG .22 bolt and carrier, modded dust cover and additional shell deflector.
Forward assist is locked in place
Has the modded charging handle, ie with shallow groove, as there is no gas tube required.
MAE rimfire suppressor (like all MAE, built like a tank)
Lower is my Spikes with carbine buffer with NZ made Katipo thumbhole stock. I've put heavier Schmeisser trigger springs to help with .22 ignition.
Mag says 15, but 14 rounds is max, have 4x 10 rounder Black Dog mags coming from Brownells.
Like all AR .22s they are quite picky with ammo, this really only likes CCI 'Suppressor' subs and CCI Minimags.
Accuracy is acceptable, 1" at 50m with the subs and 2" at 100m.
A fun gun to shoot, especially when people think its going to be a .223 and wonder why its so quiet.
