Rifle Chassis
A chassis replaces your factory stock with a rigid, machined platform that locks the action in place and floats the barrel. The result is a repeatable bedding surface, an adjustable fit, and room to add the bipods, barricade stops and accessories that precision shooting demands. We carry chassis from MDT, KRG, XLR, Grey Birch and Victor Titan for the rimfire and centerfire actions our customers build on most.

Choosing a Rifle Chassis
Fitment comes first
Every chassis is machined for a specific action footprint. Confirm your make, model and action length (short or long action for centerfire) before anything else. Barrel contour matters too: a chassis forend needs clearance around your barrel to keep it free-floated.
Magazines
Many centerfire chassis feed from detachable box magazines, often AICS pattern, while rimfire chassis typically use the rifle's factory magazines. Each listing notes what it accepts. Browse AICS magazines, rimfire factory magazines and magazine parts to complete the setup.
Ergonomics and adjustability
Adjustable length of pull and cheek height let you build a consistent cheek weld behind any optic. Grip angle and forend shape affect how the rifle settles on a bag or barricade.
Finish the build
Most chassis use M-LOK and ARCA-compatible surfaces. Add chassis accessories, a bipod, and mounts and rails to make the rifle yours. A chassis is also the right time to step up to a match-grade barrel and quality glass: browse rifle scopes and scope rings to complete the rifle.
Chassis FAQ
What is the difference between a chassis and a stock?
A traditional stock is molded or carved, and the action is often bedded into it. A chassis is a machined, usually aluminum, platform with a built-in bedding surface that holds the action consistently and free-floats the barrel, with adjustable furniture added on.
Do I need to bed my action in a chassis?
Generally no. The machined bedding surface is designed to hold the action without additional bedding. Torque the action screws to the manufacturer's spec for consistent results.
Will a chassis fit my barrel?
Most chassis clear factory and common aftermarket contours, but heavy or oversized barrels may not fit every forend. Check the barrel channel or contour notes in each listing before ordering.
What tools do I need to install a chassis?
Usually just the correct drivers and a torque wrench for the action screws. Some chassis also need the trigger guard or bottom metal swapped.
