TAPCO MILSPEC T6 AR STOCK
The TAPCO extension tube is not just made to Mil-Spec profile, all finishes and materials are as required by military specifications. The tube is made of 7075 T6 Aluminum, the same material as most AR receivers. Each tube then has the threads rolled on, a Mil-Spec process superior to standard “cutting” of threads into metal. The inside of the tube is coated with Mil-Spec dry film lubricant that not only keeps the action quieter; it reduces metal-on-metal contact, extending the service life of your buffer. While most other tubes are anodized or have no finish, the outside of the TAPCO tube is grit blasted to leave a non-reflective surface, then coated in Mil-Std 171 Lusterless Black for a smooth matte finish. The TAPCO tube is made 100% inside the U.S.A. and they provide a certificate proving it. At $105 this is definately a stock to take a look at. It installs easy and is very durable as a MIL-SPEC product should be.
