Strike Industries Advanced Receiver Extension (Black)

Original price was: $52.95.Current price is: $49.95.


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.

    Amazing buffer tube has so many slots sp you aren’t stuck with just 1 I love these wish I bought one for the build I just did because it’s super tough with Judy the 1 holder slot to catch the spring highly recommended and Andy at grendel hunter IS THE BEST trust me the 308 has its advantages but the 6.5 grendel drops deer at a flat jacktaory this is the best site if you are looking to upgrade to a grendel
