The Mission First Tactical React Magwell vertical grip for AR-15 is a purpose-built support-hand accessory engineered to improve control, accuracy, and safety during close-quarters and CQB engagements. This compact polymer grip positions your support hand forward of the magazine well, keeping your hand clear of the magwell opening—critical protection if an overcharged round causes unexpected magazine ejection. By anchoring your support hand lower and closer to the bore axis, the React allows you to apply rearward pressure that keeps the rifle shouldered and locked into your shoulder pocket, dramatically improving muzzle control and shot placement under stress.
Built from durable polymer, the grip is lightweight and won't add unnecessary weight to your platform. The design works seamlessly with standard AR-15 pattern rifles, fitting M4, M16, and compatible systems without interfering with magazine insertion or removal. Two pressure pad wells molded into the grip give you real estate to route wired switches for lights or lasers from both right- and left-handed positions—no need to buy multiple versions or awkwardly cable-manage around your hand.
A watertight storage compartment integrated into the grip body offers a secure stash for spare batteries, a small tool, or other pocket-sized essentials you want protected from the elements. Everything about this grip's design reflects Mission First Tactical's practical approach to AR-15 ergonomics: it solves a real problem—forward hand placement and control—while staying out of your way and adding minimal bulk or weight to your rifle.

Yes. The React Magwell grip is designed for AR-15, M4, M16, and HK416 pattern rifles. It installs at the magwell and won't interfere with standard magazine insertion, removal, or function.
Absolutely. The grip features pressure pad wells on both the right and left sides, giving you dedicated routing channels for wired switches and cables to activate lights, lasers, or other accessories from either hand.
The integrated watertight storage compartment is designed for spare batteries, a small tool, or other pocket-sized gear you want protected from moisture and the elements while keeping it within arm's reach.
By positioning your support hand forward of the magwell and lower on the rifle, the React allows you to apply rearward pressure that keeps the rifle firmly shouldered. This leverage reduces muzzle rise, improves shot-to-shot recovery, and makes faster, more accurate follow-up shots easier—especially critical in close-quarters or defensive scenarios.
