FAB Defense FX-TFSB Adjustable Side Folding Foregrip AR-15/M4/M16 Black Polymer

The FAB Defense FX-TFSB is an adjustable side-folding foregrip built for AR-15, M4, and M16 platform rifles. Constructed from fiber-glass reinforced polymer composite with a black finish, this foregrip folds horizontally to either side and locks into seven distinct positions, allowing magazines to clear the grip without removing the shooter's support hand from the weapon.

Purpose-built for tactical and CQB applications, the FX-TFSB adds a secure, ergonomic vertical control point that enhances overall weapon handling and improves muzzle discipline during rapid engagements. The unit mounts via a quick-detach (QD) locking lever for fast, tool-free installation and removal.

Its side-folding configuration keeps the foregrip tucked out of the way when not in use and offers multiple deployment angles to suit varied shooting positions and terrain. Whether run on a defensive carbine, a duty rifle, or a competition build, the FAB Defense FX-TFSB delivers adjustable, reliable foregrip performance in a lightweight polymer package.
