Description
The MDT Field Stock is one of the smartest upgrades you can make to a Ruger 10/22, and it hits a sweet spot between a traditional stock and a full-blown aluminum chassis. At its core sits a 6061 aluminum v-block bedding system wrapped in an overmolded polymer shell, which means you get the rigidity that helps accuracy without the cold, clubby feel of a bare metal chassis in winter. The barrel sits fully free-floated, so your groups aren't fighting pressure points like they do in the factory stock.
What Sets the MDT Field Stock Apart
This stock is built to grow with you. The buttstock adjusts for length of pull from 13.5 inches to 14.5 inches using 1/4 inch spacers, and the cheek riser is adjustable for a proper cheek weld behind glass. That kind of fit tuning is usually reserved for pricier precision setups, and it makes a real difference whether you're a smaller-framed shooter or someone bundled up in a heavy jacket. The vertical grip gives you a more natural, repeatable hold than the old-school 10/22 pistol grip.
Mounting Options on the Field Stock Forend
The long, flat-bottomed forend is loaded with M-LOK slots along the bottom and both sides, so bolting on a bipod, Arca adapter, or weights for positional work is simple. MDT also includes sling swivel studs on both the forend and the buttstock, giving you traditional sling and bipod mounting right out of the gate. That extra forend length is genuinely useful for balancing a 10/22 in field positions, which is a common gripe with shorter stocks.
Why the MDT Field Stock Is Worth the Swap
Installation is about as easy as it gets. The trigger guard is built into the stock, so you drop your barreled action in, snug the action screws, and you're shooting. It comes in at roughly 3.1 pounds and measures 32.22 inches overall. Whether you're building a rimfire trainer, a plinker, or a dedicated rimfire competition rig, the Field Stock is a quality foundation that makes a good rifle feel like a much better one.

Frequently Asked Questions
Does the MDT Field Stock fit all Ruger 10/22 rifles?
This model is designed specifically for the Ruger 10/22 in a right-hand configuration. It accepts barrels up to 1.250 inches in diameter, so it works with factory profiles as well as many heavier aftermarket bull barrels. Your barreled action drops into the aluminum v-block and secures with the included action screws.
How does the Field Stock improve accuracy over the factory 10/22 stock?
The Field Stock uses an aluminum v-block bedding system that locks your action into a rigid, consistent platform and free-floats the barrel. Removing the pressure points found in a factory stock lets the barrel vibrate the same way shot to shot, which tends to tighten up groups. Shooters routinely report better consistency after making the swap.
Is the MDT Field Stock easy to install?
Yes. The trigger guard is built right into the stock, so you drop in your barreled action, snug down the action screws, and you're ready. Most people have it done in just a few minutes with basic tools.
What can I mount on the MDT Field Stock forend?
The flat-bottomed forend has M-LOK slots along the bottom and both sides, giving you plenty of room for a bipod, Arca rail adapter, or added weight for positional shooting. It also comes with sling swivel studs on the forend and buttstock for traditional slings and bipods. The extra forend length helps balance the rifle in field positions.
