Ultradyne UD6 Picatinny Chassis Remington 700 SA Black

Description

The UD6 Picatinny chassis takes the proven UD platform and upgrades it with a modern quick-detach rear mount. Instead of being locked to a buffer tube, your buttstock now clamps to a 1913 Picatinny rail at the rear. This means you can swap stocks, break your rifle down for travel, or stow it in a tighter space without worrying about losing your zero or having to re-sight your optic.

Manufactured from a single piece of 6061 T6 aircraft aluminum, this chassis balances strength with lightweight handling. The one-piece construction weighs between 1.1 and 1.5 pounds depending on configuration, which keeps your overall rifle weight down while maintaining the rigidity needed for precision shooting. It accommodates rifles ranging from 6 to 16 pounds, working equally well for compact hunting builds or heavier long-range setups.

Design That Puts You in Control

Ultradyne prioritized ergonomics here. The adjustable grip system lets you tune trigger-finger distance to your preference, while the adjustable thumb rest positions for both repeatability and comfort. A dedicated spare-round holder keeps two extra rounds accessible without rattling around. The integrated ARCA rail runs the full length of the forend and includes M-LOK slots on three sides for mounting bipods, lights, barricade stops, or other precision accessories. V-channel bedding accommodates free-floated barrels up to 1.35 inches in diameter, and you can bed the recoil lug for even tighter control.

Built for Real Use

The chassis accepts AICS-pattern magazines and works with any standard AR-pattern grip. A forward spigot location gives you the option to extend the ARCA rail further out front if you need more real estate for accessories. A night vision bridge mount is also compatible if you decide to add thermal or night vision optics down the road. Dynalock technology ensures your action stays locked in place without play. When paired with Ultradyne's adjustable butt stock, you can add up to 5 pounds of optional weight to fine-tune balance and recoil management. All Ultradyne Remington 700 chassis are made in the United States.
