I’ve always been a sucker for the good looks of the Colt DoE upper but never liked the recoil impulse of it in 9mm. 22LR setup has the good looks but of course hardly any recoil.
Parts List:
H & R slick side upper
RRA Deflector and port door
DoE clone front site assembly from Garrison (available from Sherluk https://www.sherluk.com/m16f.php)
Two piece handguard assembly sourced 10+ years ago and no longer available. You can get one piece from Garrison / Sherluk but bear in the mind that the original was two piece.
Barrel – New RTB 22LR barrel that is CMMG / RTB / Borebuddy collar compatible. Barrel was cut down and threaded 1/2-28. I just put some cold blue on the barrel before assembly.
