Strike Industries Aluminum 7075-T6 Advanced Receiver Extension for M4 GBB Rifle (Blue)

The Strike Industries Advanced Receiver extension 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. Upgrade your AR and stand out from the pack with the SI Advanced Buffer Tube.
