The Great Little Mount is a four-slot Picatinny rail that attaches to the U.S. military-specification bayonet lug of ARs and other rifles, allowing the fitting of a light, laser, vertical grip or bipod.
The U.S.-made G.L.M. is machined from 6061 aluminum and hard-anodized. Its push-button catch allows for quick attachment and detachment of accessories, and it can be locked in place with an included set screw and Allen wrench. Custom laser engraving is also available. Price: $57.
