So I just finished this the other day. (even though some think if needs a rail and a brace.

)

4.5" Dedicated .22lr upper with CMMG bolt carrier group. (Dedicated, not conversion.) 1/16 twist. Slickside upper receiver.
Franklin Binary trigger, CMMG lower parts, Aero Precision (Burst Mode) lower receiver, Hogue grip. (Scope is 1-4, CP Tactical -pretty cheap but works fine on a .22lr.)
