The Dirty Bird CA Compliant AR-15 is built upon a top-tier Forged Upper Receiver that has been finished with Dirty Bird’s 15” SMRS M-LOK Handguard. Our California Compliant AR-15 is chambered in 5.56 and is paired with a low profile, nitride gas block, stainless steel gas tube, and nitrided flash hider. We are firm believers in having a top-quality BCG for your rifle as it is the heart of the gun. This is why our AR’s are paired with our Black Nitride 9310 steel Bolt Carrier Group. Each BCG is MPI Tested.
Our Dirty Bird lowers are forged from 7075-T6 aluminum and are Mil 8625 Type 3 Class 2 hard-coat anodized, just as our uppers. These lowers feature mil-spec lower parts kits and then we finish off the lower with a M4 carbine Mil-Spec stock and pair it with our Dirty Bird carbine buffer kit. All rifles come equipped with a M4 Stock and A2 pistol grip.
To make our AR’s compliant, we teamed up with the team at Compmag.
