Dirty Bird PCC (9mm / .45) Receiver Extension / Buffer Kit

Dirty Bird PCC (9mm / .45) Receiver Extension / Buffer KitThe Dirty Bird PCC (9mm / .45) Receiver Extension / Buffer Kit cuts no corners. It features a true Mil-Spec 6-Position Receiver Extension (buffer tube) machined from American-made 7075-T6 Aluminum, an 8-oz Extended Recoil Buffer with tungsten/steel counterweights, a chrome-silicon buffer spring, a hardened castle nut with staking cuts, and a Mil-Spec end plate.When it comes to your buffer system, quality counts. If the spring rate isn't correct, it can cause cycling issues. If your buffer uses a solid weight instead of free-moving, separate counter weights, it can cause bolt bounce. Poor quality aluminum can lead to a fracture in the receiver extension. Unfortunately, there are numerous receiver extension/buffer kits on the market (both imported and domestic) that suffer from one or more of these shortcuts in the manufacturing process.You have Dirty Bird's word that this kit is made from the finest materials and utilizes modern manufacturing processes.
