.308 Buffer Tube Kit

Dirty Bird .308 Buffer Tube KitThe Dirty Bird AR-10 / LR-.308 Carbine Receiver Extension / Buffer Kit features a true Mil-Spec 6-Position Receiver Extension (buffer tube) machined from American-made 7075-T6 Aluminum, a 3.5oz Carbine Recoil Buffer with/ 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 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 and manufactured using modern processes. If you're looking for true mil-spec quality, don't pay more -don't settle for less. This is your kit.Features 7075 - T6 Aluminum 6-Position Mil-Spec Receiver Extension 3.5 Oz LR-308 Recoil Buffer 304 Stainless Steel Construction Sliding Steel Counter Weights Chrome Silicon LR-308 Carbine Buffer Spring w/Black Oxide Finish Mil-Spec End Plate Hardened Cast Nut w/Staking CutsMade in the USABacked by Dirty Bird Industries' Limited Lifetime Warranty
