Description
The MDT Field Stock lands in that great middle ground between a wobbly factory polymer stock and a four-figure competition chassis. It's built for folks who already love their Ruger 10/22 and want a genuine accuracy bump without paying a gunsmith or guessing their way through a project. The core is 6061 aluminum wrapped in overmolded polymer, so you get a rigid backbone with a traditional feel that stays comfortable in your hands on a cold morning at the range.
What the MDT Field Stock Does for Your 10/22
The real magic here is the aluminum V-block bedding paired with a free-floating barrel channel. The V-block gives your receiver a stable, repeatable seat that stays put round after round, and free-floating the barrel takes away the pressure points a factory stock introduces. A stock alone won't fix a mediocre barrel, but pull the flex and slop out of the equation and a good 10/22 will start printing noticeably tighter groups. One shooter running a quality build reported half-MOA results, which tells you the platform isn't holding anything back.
Dialing In the Field Stock
Fit matters, and this chassis gives you plenty to work with. The length of pull adjusts from 13.5 to 14.5 inches using quarter-inch spacers, and the integrated cheek riser raises and lowes to lock in a repeatable sight picture behind whatever glass you're running. The buttstock adjustments are tool-free once you've got it apart, so getting comfortable behind the rifle is quick.
Building It Out Your Way
The M-LOK forend opens the door to bipods, sling mounts, and other accessories, and MDT includes sling swivel studs so you can hang a sling right out of the gate. The mounting setup is genuinely clever: a longer buffer pin anchors the rear while nylon dowel pins crush into place at the front hold-down bolt, creating a rock-solid two-point lockup. It runs your standard Ruger 10/22 rotary magazines with the latch built right into the bottom metal, so there's no chasing down special mags.

Frequently Asked Questions
Will the MDT Field Stock actually tighten up my groups?
The V-block bedding and free-floating barrel remove the flex and movement that factory stocks introduce, which is where most accuracy gains come from. If your barrel and ammo are decent, most people see measurable group tightening once everything is torqued and set up right. The stock can't turn a poor barrel into a tack driver, but it lets a good one reach its potential.
Does the Field Stock work with my standard Ruger 10/22 magazines?
Yes. It's designed around standard Ruger 10/22 rotary magazines and factory-style clones, and the magazine latch is built right into the bottom metal. You can keep running the mags that came with your rifle with no adapters needed.
How hard is it to install the Field Stock on a 10/22?
It's a straightforward drop-in with basic hand tools. The rear anchors using a longer buffer pin and the front locks down with a V-block and single action screw, with nylon dowel pins that crush into place for a tight fit. Most owners have it swapped over in a few minutes without any gunsmith work.
Can I adjust the cheek riser and length of pull?
Both are adjustable. Length of pull runs from 13.5 to 14.5 inches using the included quarter-inch spacers, and the integrated cheek riser raises to give you a repeatable cheek weld behind your optic. The riser adjusts tool-free, though you'll need to pull the action to change the length-of-pull spacers.
