Strike Industries Advanced Receiver Extension (AR 15/10 Buffer Tube)

The Strike Industries Advanced Receiver extension brings an updated aesthetic and increased functionality to an often neglected, yet highly important component of the AR-15/AR-10 weapon system.  The scalloped surfaces decrease friction with tight fitting stocks, and shaves weight while retaining mass in critical stressed areas.  Further enhancements include a supported buffer retaining tab that also serves to more easily index your receiver extension.  The SI Advanced receiver extension is machined from 7075-T6 aluminum for much greater strength than your standard 6061 tubes.  Upgrade your AR and stand out from the pack with the SI Advanced Buffer Tube.
