Bushmaster Carbon upper in .22lr comes complete with bolt, charging handle, and 10-rnd mag. The barrel has been custom threaded 1/2 x 28 to accept suppressors. I used this setup in conjunction with a TAC-65 suppressor for very accurate, quiet shooting. The plastic magazine is cracked but fully functional. Approximately 500 rounds through this upper. SPF.
Second upper is sold.
Thanks for looking.
