From the manufacturer
With the popularity of short, pistol-length, AR-style firearms on the market, more of today's AR owners are seeing a phenomenon that occurs on semi-automatic firearms with short gas systems: overgassing. The result of overgassing is increased wear on internal components, as well as increased felt recoil. To address these issues, Aero Precision launched its AR-15 Carbine Buffer Kit. Several options are available in the company's Carbine Buffer Kit lineup. Each kit ships with a mil-spec buffer tube machined from 7075-T6 aluminum and features slots for a six-position buttstock. The kits also include a buffer spring, end plate and castle-lock nut. However, where the kits differ i Mfg: Aero Precision
