Built around real-world ergonomics, the BCM Mod 3 Vertical Grip is an ultra-light version of our Short Vertical Grip that directly attaches to either a KeyMod rail system (Mod 3 - KM) or Picatinny rails (Mod 3 - 1913) using a patent pending snag free internal mounting system. Developed by the BCM Engineering Team, the BCM Mod 3 Vertical Grip is an ultra-compact and ultra-light accessory designed to improve the shooters interface with the weapon.Features: Low-profile length for increased mobility and decreased snag factorThe forward angle increases the rigidity of the forearm, while providing a more natural wrist angleCan be mounted in reverse angle to increase control when grabbing handguard and gripFlat sides give better yaw control to the shooter during firing and non-firing manipulationsAggressive texture and storage volume combined with modular design to allow improvements and adaptation in the futureCross bolt designed to work with improvised tools (such as a quarter) and allow for easy adjustment or re-tighteningReversible clamps allow user to setup fasteners to reside on either sideSpring-loaded clamp makes installation and removal easierMade in the USA and manufactured from high quality, impact resistant polymersTest fit to ensure proper function (may display attributes consistent with this QC process)
