Purchase the Dirty Bird 10.5″ Government Carbine 5.56 M-LOK Upper Assembly here!

This Dirty Bird Industries Complete Upper features a Black Nitride 10.5” Government Profile barrel chambered in 5.56 with a 1:7 twist. Built on a top-tier Forged Upper Receiver and finished with Dirty Bird’s 9.7″ SMRS M-LOK V2 or V3 Handguard available in several color options. No corners are cut when manufacturing these complete uppers. All barrels are dimpled and cold blued, use a .750 black nitride 4140 steel gas block and a carbine stainless steel gas tube. The gas block set screws feature knurled cone tops and are installed using blue locktite ensuring that no amount of firing will cause the set screws to come loose but they will still able to be removed for servicing if needed.

NEW: The Dirty Bird SMRS Handguard featured our new Rock Solid Patent Pending Anti-Slip / Anti-Lift attachment system. The clamp-on style of handguard attachment, utilized by many manufacturers is both secure and convenient but one problem has always been that clamping the handguard it tends to lift the front end of the handguard. The longer the handguard, the more drastic the effect. If you’ve ever had to bottom-out the front-sight post of a rail mounted BUIS in order to get the correct elevation, the issue is probably due to this “”lift”” phenomena.
