Designed to work with both AR-15 and AR .308 platforms, this Crosstac Aluminum Armorer Block Kit includes features designed to secure both the upper and lower receivers of these popular platforms:
- Adjustable block that covers all platforms
- Holds your receivers more securely than other armorer's blocks on the market
- Nylon setscrews for precision adjustment inside the magazine well
- Machined ledges in the base of the rest for level positioning
- CNC-machined stainless-steel pin driver included
