Independent Review Strike Industries is proud to introduce our improved 7-position (That's right not 6 position but 7) Aluminum receiver extension MIL-SPEC diameter buffer tube. It will allow users to have finer control of their length of pull. If you have ever felt that your length of pull was in between two settings on a standard buffer tube, this is for you! The tube's shortest length of pull position is as compact as a fully collapsed M4 carbine butt stock while its longest 7th position stretches the stock to be slightly longer than that of an M16A2 fixed stock.
