Dirty Bird Slick-Side 16" 9mm 1:10 M-LOK Complete Upper

This Dirty Bird Industries 9mm Complete Upper features a PCC (Pistol Caliber Carbine) upper receiver with a Last Round Bolt Hold Open (LRBHO) mechanism and pairs it with one of the best-selling 15″ Dirty Bird SMRS M-LOK Handguards. Every part was selected meticulously to provide the best experience.

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. The ASAL system means that you don’t have to worry about any unwanted “lift”.
