The Accu-Shot Folding Vertical Fore Grip offers two opposing flat surfaces to secure light switches with the installed Buna O-Rings. Removing the bottom cap will reveal a storage compartment designed to hold a single 123 battery. The unique design protects the battery from being drained by placing the positive side (+) towards the relieved cap. When folded, the profile is reduced for a cleaner presentation for lower rifle positions as well as reducing the stop or snag point found with fixed vertical fore-grips. Like all our products, it’s constructed of the finest materials and built to the highest standards right here in the USA. Available in black only. Length 4.15” deployed, 1.35 folded.
