Why Choose the ATI Shotforce GEN2 Shotgun Stock?
The ATI Shotforce GEN2 Shotgun Stock is designed for shotgun owners who want the adjustability of a modern stock system without replacing the firearm platform they already know and trust.
Traditional fixed shotgun stocks provide one length of pull and limited flexibility. The Shotforce GEN2 adds an adjustable stock system that allows the shotgun to be configured more comfortably for different shooters, shooting positions and intended uses.
Adjustable Fit Without Changing Your Shotgun
The Shotforce GEN2 uses ATI's six-position adjustable stock, allowing the length of pull to be changed quickly to better fit the individual shooter.
That adjustability can be especially useful when shooting positions or clothing change, or when the same shotgun may be used by shooters with different fit requirements.
ATI's TracLOCK system is designed to provide smooth, secure stock adjustment while helping reduce unwanted horizontal and vertical movement between the stock and buffer tube.
Designed for Comfort and Recoil Management
A shotgun stock has a direct effect on how recoil feels and how comfortably the firearm can be controlled.
The Shotforce GEN2 incorporates ATI's recoil-reducing butt-pad to help absorb recoil impact and improve shooting comfort. Combined with the adjustable stock configuration, the system provides an alternative to the fixed dimensions of a traditional factory shotgun stock.
The result is a stock system designed to improve fit and comfort while retaining the familiar operation of the original shotgun.
Built for Proven Shotgun Platforms
The Shotforce GEN2 was developed for several of the most widely used pump-action shotgun platforms.
Applications include select Mossberg 500, 535, 590 and 835, Maverick 88, Remington 870, and Winchester 1200 and 1300 shotguns.
ATI uses model-specific adapters to allow one stock system to work across multiple supported shotgun families.
Because firearm configurations, gauges and production years can vary, always review the ATI Fitment tab before ordering.
The ATI Advantage
ATI develops firearm accessories to give owners practical ways to improve the fit, comfort and functionality of firearms they already use.
The Shotforce GEN2 applies that philosophy to some of America's most established pump-action shotgun platforms by combining an adjustable stock, secure stock-locking system and recoil-management features into one adaptable upgrade.
For owners looking to modernize a Remington 870, Mossberg 500 or 590, Maverick 88 or another supported shotgun, the Shotforce GEN2 provides an ATI-designed adjustable stock solution while maintaining the familiarity of the original firearm.

every part was accounted for, it fit perfectly on my Mossberg Maverick 88 security, and its made my shooting experience 100x better.
It fit my mossberg 500 and was easy to install. The price was right and I wanted something inexpensive for the shotgun I keep in my truck. This fit the bill.
Great product. Fit perfect. Been out a couple of times at the range and we love it
Everything I expected and more.
Great company
