The Adaptive Tactical EX Performance Forend & Adjustable Stock for Remington 870 12-gauge shotguns is a purpose-built polymer upgrade kit designed to modernize your pump shotgun with tactical features and shooter comfort. Built from durable, lightweight high-impact polymer and made in the USA, this two-piece system replaces your factory stock and forend with components engineered for faster target acquisition, easier accessory mounting, and personalized fit—making it a smart choice for home defense, sport shooting, or tactical training.
The adjustable stock features a pistol grip and rapid-adjust lever that lets you dial in your length of pull on the fly, so you can find the perfect fit whether you're running the gun in a t-shirt or heavy gear. The stock spans from 11.5 inches (without the recoil pad) to 15 inches (with pad) at maximum extension, and includes integrated sling attachment points plus a standard molded swivel attachment. A cushioned, non-slip vented rubber recoil pad tames 12-gauge impulse, and the oversized adjustment pin reinforces the mechanism for hard use.
The forend houses a 2-inch Picatinny rail concealed under a nose cap that can be removed to mount lights, lasers, or other tactical accessories directly to your pump gun. Like the stock, it's built tough in lightweight polymer and designed for owner installation without gunsmithing. Color options include black for traditional use or orange for less-lethal and law enforcement training applications where visibility matters.
This kit is optimized for standard Remington 870 12-gauge pump shotguns. Note that it is not compatible with the Remington 870 Super Magnum or recommended for use with the TAC-14, as it creates a short-barreled configuration on those platforms.
