Video | What’s Included | Specs | Pictures | Restrictions

The BEV Block is a multi-purpose vise block tool that engages the barrel extension to provide safe installation of barrel nuts and flash hiders. The steel lugs are strong enough to have lasting durability but not hard enough to damage your barrel. The BEV Block can also be flipped upside down to be used as a magwell block, making this an excellent addition to any workbench.
