The Harris S-BR2 Bipod Sling Swivel Stud Mount allows the shooter to quickly set up on uneven surfaces and adjust the leg height without leaving their position. The Bipod is self leveling and just takes a simple twist of the locking mechanism to keep it in position. The S-BRS uses a the same Harris classic base, the S Series which rocks from side to side.FeaturesExtends from 6" to 9"Swivels (tilts) to compensate for uneven terrainQuick Deploy spring loaded with self-leveling legs Attaches to the Sling Swivel StudUltralight weight - 14 ozHas a built-in sling swivel stud to attach the slingMost useful for shooting off the bench
