Looking to sell my CMMG upper with Troy Alpha rail. It is chamber in 300 Blackout with a 16" stainless steel barrel. I shot both 220 subsonic and 110 superonic through the rifle both producing around a 1moa groups. Upper has about 35 rounds and I could include a 100 rounds of subsonic with the purchase and a 30 round p-mag. I am asking a 1000 for upper, rail, ammo and magazine. Scope, mount and suppressor are not included.
