Why Choose the ATI T3 GEN2 Shotgun Stock?
The ATI T3 GEN2 Shotgun Stock is designed for shotgun owners who want a more adjustable, comfortable and versatile alternative to a traditional fixed factory stock. Rather than changing the character of a proven shotgun platform, the T3 GEN2 gives owners a way to modernize the stock system while keeping the firearm they already know and trust.
A Better Fit for More Shooters
Traditional shotgun stocks typically have a fixed length of pull. That can work well for some shooters but may be less comfortable when shooting positions, clothing or individual body size changes.
The T3 GEN2 uses ATI's six-position adjustable stock system, allowing the shooter to change the length of pull to better fit their needs. The adjustable design can also make the shotgun easier to configure for different shooting positions and users.
Designed Around Comfort and Control
Shotguns can produce substantial felt recoil, especially with heavier loads. ATI designed the T3 GEN2 with recoil management and shooter comfort in mind.
The system combines ATI's X Series recoil-reducing pistol grip with a thick recoil-reducing butt-pad. The pistol-grip design provides a secure gripping surface, while the stock configuration gives the shooter additional adjustability compared with a conventional fixed stock.
ATI's TracLOCK GEN2 system is also designed to provide smooth stock adjustment while helping reduce unwanted movement between the stock and buffer tube.
Built for Popular Shotgun Platforms
One of the advantages of the T3 GEN2 is its multi-platform design. Rather than being limited to a single shotgun family, the system supports a range of popular pump-action shotguns.
Applications include select Mossberg 500, 535, 590, 590S and 835, Maverick 88, Remington 870 and 887, Winchester SXP, Savage Stevens 320, and other supported shotgun models.
Because individual models, gauges and production years can vary, always review the ATI Fitment tab before ordering.
The ATI Advantage
ATI develops firearm accessories around a simple goal: give owners practical ways to improve the fit, comfort and functionality of firearms they already use.
The T3 GEN2 brings that approach together in one adjustable shotgun stock system by combining multi-position adjustment, recoil-management features, ergonomic control and broad shotgun compatibility.
For owners looking to upgrade a Remington 870, Mossberg 500 or 590, Maverick 88, Winchester SXP or another supported platform, the T3 GEN2 offers a purpose-built ATI solution without giving up the familiarity of the original shotgun.

I love this stock just put it on my mossburg 500c 20 gauge that ive had since i was 10 years old. I am now 49 and wanted to give my 20 gauge ive had forever some love.Says its proud fit but it is very slight proud fit. Very well made and easy to put on. I will be purchasing another 1 for my 12 gauge. A+++
Love it great fit for my RIA vrpa 40 12 gauge, gives you multiple adaptors for a tight fit,but don’t list it on fitment for it..but it’s absolutely great stock..thank you .
I love these stocks. Hope to eventually have them on all my shotguns.
Attached to a home defense shotgun. Makes the firearm usable for more members of the household. OSFA
Very easy installation and great stock for all the way in is any shotgun. LOP with stock all the way in is perfect for me. The grip angle is just right for an old guy and the recoil pad works well. I have already ordered another one for my other shotgun.
