CATS 3 (Combat Air Thru Stock)

MILSIG CATS – The Industry Standard for Air Through Stocks

The CATS (Combat Air Through Stock) originated by MILSIG has built such an legendary reputation that the name is now used as the generic term for an air through stock. How cool is that?

The CATS has become the staple of tactical setups for a reason. Its reinforced attachment point removes unnecessary stress from your ASA threads, while the integrated air fitting offers a 60-degree rotation—ensuring your remote line never jams into your wrist or creates an awkward shooting angle.

Key Features of the Generation 3 CATS:

• Signature Rotating Fitting – The CATS features a unique rotating elbow that moves as fluidly as you do. Say goodbye to remote lines sticking straight down into your wrist; our fitting adjusts to your movement.

• Mil-Spec Compatibility – Built to standard Mil-Spec sizing, the CATS allows you to attach any Mil-Spec buttstock, giving you endless customization options.

• Maximum Rigidity – By coupling the new rotation system with a "beefed-up" structural design, the Generation 3 is the most rigid and durable air-thru stock we have ever produced.

Specifications:

• Weight: 400g

• Material: High-grade reinforced alloy

• Fitting: 60-degree fluid rotation

• Compatibility: All MILSIG markers and standard Mil-Spec buttstocks

The Original. The Best.

When you choose the MILSIG CATS, you aren't just buying a buffer tube—you’re buying the original innovation that defined the category.
