GG&G AR-15 Vertical Foregrip with Waterproof Compartment

GG&G's AR-15 vertical foregrip mounts to a Picatinny rail and gives a stable, 4.5" long grip. The body hides an O-ring sealed waterproof compartment reconfigured to hold a spare AR-15/M16 bolt securely.

Without the bolt, it fits two AA or two CR123 batteries, or small parts like firing pins and extractors (pack them so they do not rattle). Every part is CNC machined from solid black acetal polymer rather than molded, and the Tri-grip cap is shaped not to snag. No special tools are needed to install or adjust it.
