Further enhancements include a supported buffer retaining tab that also serves to more easily index your receiver extension. Features 7-position MIL-SPEC diameter buffer tube, fits onto any standard AR15 receiver, finer length of pull adjustment, supported buffer retainer and compatible with Strike Industries Pit Viper Stock.
