Ati Outdoors C1102007 T3 Gen 2 Shotgun Stock Urban Gray Fits Remington 870/Mossberg 500/Winchester Sxp

The Advanced Technology T3 Gen 2 shotgun stock is a practical upgrade for owners of Remington 870, Mossberg 500, or Winchester SXP 12-gauge shotguns who want better ergonomics and flexibility in the field. This adjustable stock lets you dial in the length of pull between 13 1/8" and 16 5/8", accommodating different shooting positions, body types, and gear setups without swapping hardware. Whether you're running a tactical shotgun for home defense, clay shooting, or hunting, a properly fitted stock reduces fatigue and improves consistency.

Built with durability in mind, the T3 Gen 2 is constructed to handle the recoil and wear that comes with regular use. The urban gray finish blends function with a clean, modern look that works on modern or traditionally styled shotguns. The 6-position adjustable design means you're not locked into a one-size-fits-all setup—you get real versatility for a modest investment.

Installation is straightforward on any of these three platforms, making this a no-fuss upgrade if you're already familiar with your shotgun's controls and takedown. Advanced Technology has focused on getting the fundamentals right: solid manufacturing, proven compatibility, and a stock that stays put under use.

Frequently Asked Questions

Does this stock fit my Remington 870, Mossberg 500, or Winchester SXP?

Yes. The T3 Gen 2 is specifically designed to fit all three of these 12-gauge shotgun platforms. Verify your shotgun model before purchase to ensure compatibility.

What is the adjustable length of pull, and why does it matter?

This stock adjusts from 13 1/8" to 16 5/8" across 6 positions. Length of pull (LOP) is the distance from the trigger to the rear of the stock. Having the correct LOP improves your shooting form, reduces recoil felt, and lets you mount the gun consistently. Different shooters and different gear setups require different lengths, so adjustability is a real advantage.

Is installation complicated?

Installation is straightforward on these shotgun platforms if you're comfortable with basic takedown and reassembly. Consult your shotgun's manual or a gunsmith if you're unfamiliar with the process.

What does Mil-Spec mean?

Mil-Spec refers to military specification standards for materials, tolerances, and performance. Products built to this standard are designed to handle heavy use and harsh conditions reliably.
