Why ATI

Why Choose the ATI T3 Shotgun Rear Pistol Grip Combo Package?

The ATI T3 Shotgun Rear Pistol Grip Combo Package is designed to give compatible shotguns a more ergonomic rear-grip setup while providing the components needed for a coordinated T3 conversion.

It is a practical option for owners who want improved grip control, a more modern handling feel and ATI platform compatibility in one package.

T3 Rear Pistol Grip Design

The T3 rear pistol grip provides a more defined hand position than a traditional straight shotgun stock.

Its shape is designed to give the shooter a secure, comfortable grip while maintaining straightforward access to the shotgun’s controls.

Coordinated Combo Package

The combo-package format brings compatible T3 components together rather than requiring the owner to source individual pieces separately.

That makes it easier to create a unified setup with components designed to work together.

Improved Handling and Control

A rear pistol grip can provide a more natural wrist angle and a firmer grip on the shotgun.

This can make the firearm more comfortable to handle during range use, maintenance and general operation, especially for shooters who prefer a pistol-grip-style interface.

Durable Synthetic Construction

The T3 system uses durable synthetic components designed for regular use and changing environmental conditions.

Synthetic construction also provides a practical alternative to traditional wood furniture when replacing worn or damaged stock components.

Supports Multiple Shotgun Platforms

The T3 product family is designed around several popular shotgun platforms, including compatible Mossberg, Remington and Winchester models.

Because mounting requirements differ between models, the correct adapter or configuration must be selected for the individual shotgun.

Always review the ATI Fitment tab before ordering.

Practical Upgrade or Replacement Package

The T3 Rear Pistol Grip Combo Package can be used when modernizing an existing shotgun, replacing damaged furniture or changing the rear-stock configuration.

Its modular design gives owners the ability to build around compatible ATI components as their setup changes.

The ATI Advantage

ATI’s T3 system is built around firearm-specific fitment, modular components and improved ergonomics.

The T3 Shotgun Rear Pistol Grip Combo Package brings those features together in a coordinated upgrade designed to give compatible shotguns a comfortable, durable and modern rear-grip configuration.
