ATI Outdoors
Authorized Dealer • Made in Grafton, Wisconsin
ATI Outdoors (Advanced Technology International) manufactures aftermarket firearm furniture in Grafton, Wisconsin — the polymer Strikeforce, TactLite, Shotforce, and T3 Gen2 stock lines that have replaced factory wood and basic synthetic furniture on millions of Mossberg 500 / 590, Remington 870, Winchester SXP, AR-15 / AR-10, AK-47, Ruger 10/22, Mosin-Nagant, and Mauser 98 platforms across the American shooting market. Keep Shooting carries ATI's universal-fit 12 gauge shotgun pistol-grip stock and the deluxe heatshield with integrated ghost-ring sights.
About ATI Outdoors
ATI Outdoors (Advanced Technology International) is the Wisconsin-based aftermarket firearm furniture manufacturer that has been replacing factory wood and basic synthetic stocks for decades. The company manufactures in Grafton, Wisconsin and has built its reputation on the Strikeforce, TactLite, Shotforce, and T3 Gen2 stock families — drop-in polymer replacements for the most popular American pump shotguns, sporting rifles, and surplus bolt-action rifles. Keep Shooting carries ATI's universal-fit 12 gauge shotgun pistol-grip stock and the deluxe shotgun heatshield with integrated ghost-ring sights, both compatible with the Mossberg 500 / 590 and Remington 870 platforms we stock heavily on the shotgun and Mossberg parts sides of the catalog.
Universal 12 Gauge Pistol-Grip Stock
The ATI Universal 12 Gauge Shotgun Pistol-Grip Stock is the workhorse drop-in replacement for factory wood and basic synthetic stocks on the dominant American 12-gauge pump platforms — Mossberg 500 / 590 / 590A1 / Maverick 88, Remington 870, Winchester 1200 / 1300 / SXP, and a long list of compatible variants. The ATI universal stock adds an integrated pistol grip, textured grip surfaces front and rear, and a recoil-absorbing buttpad on a high-impact glass-filled polymer body that costs a fraction of factory replacement furniture. It's the same stock concept Mossberg ships on their FLEX 500 Tactical and that Remington offers as the 870 Express Tactical — ATI was producing the aftermarket version years before either factory adopted the configuration as a standard SKU. Browse the broader shotgun catalog to pair the stock with a complete firearm purchase.
Deluxe Shotgun Heatshield with Ghost-Ring Sights
The ATI Deluxe Universal Shotgun Heatshield with Ghost-Ring Sights is a two-in-one upgrade kit: a ventilated steel heatshield that protects the support hand from a hot barrel during sustained fire (a real concern in tactical and 3-gun applications), combined with an adjustable-rear ghost-ring rear sight and front sight post. The ghost-ring optical configuration — a wide aperture rear sight paired with a contrasting front post — is the same sight system Mossberg ships on the 590A1 Special Purpose for military and law-enforcement use. The ATI kit gives shooters the same upgrade on a bead-sighted Mossberg 500 or basic Remington 870 without buying a separate factory sight-equipped variant. Cross-shop the Remington 870 parts category for additional accessories that complement the ATI sight system.
The Broader ATI Catalog
Beyond the two universal-fit shotgun accessories we currently stock, ATI Outdoors produces a much wider catalog at the manufacturer level: the Strikeforce adjustable-stock-and-forend kits for AK-47 and Saiga platforms, the TactLite AR-15 / AR-10 collapsible stock and pistol grip family, the Shotforce platform-specific shotgun stocks (purpose-built for individual receivers rather than the universal-fit pattern), and the T3 Gen2 chassis-style modular stock for Ruger 10/22 and bolt-action rifle conversions. Of note: ATI's surplus rifle stock conversions for the Mosin-Nagant, Mauser 98, and Lee-Enfield have driven much of the modern revival of these classic bolt-action rifles in American sporting use, replacing original-configuration wood with modular polymer chassis that accept Picatinny rails, scope mounts, and modern accessories. Cross-reference our Mosin-Nagant parts and Ruger 10/22 parts catalogs for the platform-specific replacement parts that pair with ATI stocks when sourced separately.
Why ATI
ATI Outdoors occupies the value-engineered middle of the aftermarket-stock market. They aren't competing with Magpul on premium polymer engineering or with Magpul's PRS precision-rifle chassis at the high end of the price band; they aren't competing with the no-name Chinese imports at the bottom either. The ATI catalog targets the shooter who wants a meaningful upgrade from factory wood or basic synthetic to a tactical or modern polymer configuration without spending Magpul money. Made in Grafton, Wisconsin means American manufacturing and warranty support without the import premium. Shop the broader shotgun category for ATI-compatible firearms, and cross-reference Magpul and ProMag for additional aftermarket furniture and magazine options at adjacent price tiers.
