T3 Pistol Grip GEN2 Shotgun Stock – Control and Comfort
At the heart of this system is ATI’s T3 Pistol Grip GEN2 shotgun stock, designed to give you a more ergonomic, rifle-like feel: riflesupply.com+1
Vertical pistol grip for improved wrist angle and better trigger control
Enhanced control in close quarters, defensive use, and fast follow-up shots
Secure grasp with gloves or wet hands, ideal for duty, home defense, or harsh weather
The pistol grip design helps manage recoil and muzzle rise by allowing a more natural, locked-in shooting stance—something traditional hunting stocks can’t always provide.
TactLite GEN2 6-Position Adjustable Mil-Spec Stock
Attached to the pistol grip is ATI’s TactLite GEN2 6-position adjustable Mil-Spec stock, giving you the ability to tailor the length of pull and overall feel of your shotgun: riflesupply.com+1
6-position collapsible design – adjust for body size, clothing layers, or body armor
Length of pull adjustable from about 13 1/8" to 16 5/8", so you can find the exact fit for close-quarters work or extended shoulder-mounted shooting
Compact for transport and carry – collapse the stock to shorten the overall length, making it easier to stow in a safe, vehicle, or patrol rack
The adjustable stock ensures your shotgun fits you, improving comfort, sight alignment, and speed on target.
TracLOCK GEN2 System – Solid, No-Wobble Lockup
Nothing is more annoying than a collapsible stock that rattles or shifts under recoil. ATI addresses this with their TracLOCK GEN2 system: tacticalsupplysource.com+1
Reduces or eliminates horizontal and vertical movement between stock and buffer tube
Provides a solid, rock-steady feel that inspires confidence on every shot
Eliminates the need for a secondary locking device
With TracLOCK GEN2, your adjustable stock feels more like a fixed stock when it’s locked into position—only with the flexibility to change length when you need it.
X Series Recoil-Reducing Pistol Grip
The T3 GEN2 stock system includes ATI’s X Series recoil reducing pistol grip, designed to help tame the punch of 12-gauge buckshot and slugs: riflesupply.com+1
Recoil-absorbing grip design helps reduce felt recoil into the shooting hand
Aids in faster follow-up shots and better shot-to-shot control
Enhances comfort during prolonged training sessions or tactical courses
Combined with a quality recoil pad on the TactLite stock, this system is built to make your 12-gauge more manageable and enjoyable to shoot.
