Dirty Bird AR-15 True Mil-Spec Carbine Receiver Extension / Buffer Kit - H1 - D254

Dirty Bird AR-15 True Mil-Spec Carbine Receiver Extension / Buffer Kit – H1

The Dirty Bird Industries Mil-Spec Carbine Buffer Kit cuts no corners. It features a true Mil-Spec 6-Position Receiver Extension (buffer tube) machined from American-made 7075-T6 Aluminum, 4oz H1 Recoil Buffer w/ 2 steel and 1 tungsten 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, 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.
