The 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, 8oz Extended Recoil Buffer, a cryogenically processed Sprinco Red Buffer Spring, hardened castle nut with staking cuts and 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. Poor quality aluminum can lead to a fracture in the receiver extension. Unfortunately, there are a ton of receiver extension / buffer kits on the market (import AND domestic) that suffer from one or all of these shortcuts in the manufacturing process.
You have Dirty Bird’s word that this kit is made from the finest materials, using modern manufacturing processes. If you’re looking for true mil-spec quality, don’t pay more, don’t settle for less; this is your kit.
