Strike Industries Advanced Receiver Extension Buffer Tube




Strike Industries Advanced Receiver Extension AR15/AR10 M16 M4 Black Blue Red Fde Anodized Colors

The Strike Industries Advanced Receiver extension Buffer Tube brings an updated aesthetic and increased functionality to an often neglected, yet highly important component of the AR15/AR10 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.
