TNA Buttstock Kit (Standard Mil-Spec)
This is a complete buttstock kit including the Buffer Tube, Buffer, standard Buffer Spring, Castle Nut, Recevier End Plate, and Tapco-like stock. Convert a fixed-stock AR-15 to an M4 configuration or complete your stripped lower on the cheap. Also useful for completing a Matador Sabertooth or other firearm chassis that uses AR stocks.
The stock is collapsible and 6-position to meet the needs of different-sized shooters in a variety of shooting positions. This is ready to install on any AR-15 lower so long as the Upper Receiver's buffer tube threads are in spec.
Stock is made from a tough injection-molded plastic. The stock interior diameter closely matches the buffer tube for a tight fit. The stock adjustment lever/button has lots of stroke to fit other applications if needed. The buffer tube is anodized aluminum for a long service life.
