This UD3 Chassis Combo takes the guesswork out of building a precision rifle around your Remington 700 short action. Instead of piecing together a chassis, stock, and grip from three different places, Ultradyne packages all of it together so you can drop your barreled action in, snug up the action screws, and get to shooting. The chassis itself is machined from a solid billet of 6061-T6 aircraft aluminum, which keeps the whole package light without sacrificing the rigidity that long range accuracy depends on.
The one-piece design of the UD3 chassis weighs in the neighborhood of 1.1 to 1.5 pounds on its own, which puts it in play for both a lean mountain rifle and a heavier long range setup. V-channel bedding cradles the action and can handle free floated barrels up to 1.35 inches in diameter, so you're not locked into a factory contour. Down below, it feeds from AICS-pattern magazines, which is about as close to a universal standard as precision rifles get these days.
Every side of the forend has M-LOK slots cut in, and there's a built-in ARCA rail running the length of the bottom, so bipods, barricade stops, and other accessories mount directly without needing a separate rail adapter. Ultradyne's Dynalock system locks the action into the chassis with a snug, repeatable fit, and the magazine release lever is adjustable so you can set it exactly where your trigger finger wants it.
The combo adds Ultradyne's Gen 2 adjustable butt stock and a compatible pistol grip to the chassis, giving you adjustable length of pull and cheek height right out of the gate. That means less time shimming spacers and cheek pads to get a proper stock weld, and more time actually getting behind the rifle. This particular version is set up for right-handed shooters running a Remington 700 short action, finished in black to keep things simple and low profile in the field or on the bench.
It includes the chassis, the Gen 2 adjustable butt stock, and a grip, which covers the platform side of the build. You'll still need to supply your Remington 700 short action, barrel, trigger, and an AICS-pattern magazine to complete the rifle.
This specific version is built for Remington 700 short action footprints, so it's meant to drop in with minimal fitting. Check your action's specific pattern before ordering since short action Rem 700 clones can vary slightly.
Yes, the included Gen 2 adjustable butt stock lets you dial in length of pull and cheek height to match your body and your optic setup. This makes it a lot easier to get consistent eye relief and a repeatable cheek weld compared to a fixed factory stock.
The chassis is built around AICS-pattern magazines, which is one of the most widely supported magazine standards in the precision rifle world. That means you've got a lot of options for capacity and materials when picking magazines to run with it.
