MR-19™ Manual Precision Rifle

Evolved from our previous generation manual rifles, the MR-19™ builds upon years of innovation in both chassis design and precision shooting technique. The result is a premier collaborative rifle system for long-range duty or competition made possible by the melding of two elements:

A precision-engineered and full-featured Deadline short action from Ultimatum Precision. Paired with a cryogenically treated JP Supermatch™ barrel and high-end match trigger, this unique short throw action offers far more than typical 2-lug Remington 700 designs.

The Advanced Precision Ambidextrous Chassis brings next generation fit and function to the bolt action. The APAC™ is a folding, ambidextrous, fully adjustable system compatible with AI-pattern magazines and all JP MK III Hand Guard accessories, including Arca-Swiss.

Complete MR-19™ rifles are available in .308 Winchester, 6.5 and 6mm Creedmoor with custom finishes available on request. For the full range of available options, spec your custom MR-19™ build in our online Rifle Builder.

Ultimatum Precision Deadline Short Action

The Deadline action is specifically designed for long range, precision shooting. Its components are made using the cutting edge of technology and subject to stringent manufacturing requirements. It features a floating and replaceable bolt head delivering ultimate accuracy and versatility.


Sturdy Rear Tang:
A sturdy rear tang ensures that the action is seated properly in the chassis/stock and that the action remains as stiff and true as possible. This helps to maintain accuracy.
20 MOA Aluminium Picatinny Rail:
Deigned to handle the heaviest optics on the market, the rail features 6x #8-40 mounting screws and 2 dowel pins. While offering the benefits of an integral rail, it also brings the versatility to choose different rail cants. Also available "flush" to the front of the receiver.
Minimal Ejection Port:
The action uses a minimally sized ejection port in order to maximize the strength and stiffness.
Removable Floating 3 Lug Bolt Head:
The floating bolt head ensures that the bolt face is always perfectly aligned to the axis of the barrel, enhancing accuracy. The dual-ejector bolt head is also removable and replaceable making caliber changes easy and quick.
4340 Steel Construction with Liquid Hard Nitride Coating:
4340 HTSR steel is used for the action housing. The hard nitride improves wear, corrosion and chemical resistance. Surface hardness is also improved with the hard nitride finish.
Gas Blocking Shroud with Anti-rotational Lock System:
The shroud to action housing fitment acts as a "wall", restricting any residual blow-back gases. The notch at the top of the bolt shroud locks rotational forces during cocking, minimizing friction to allow a lighter bolt lift.
1-1/16″ x 20 Barrel Threads:
The Ultimatum Action uses a 1-1/16″ x 20 threads. It is designed to accept savage prefit small shank barrels. A barrel machined to proper specs can also be mounted in a similar manner to the remington 700 setup.
Integral Recoil Lug:
The recoil lug is machined into the action to maximize strength and to provide additional thread interface to the barrel. It is 5/16" thick.
AICS and AW magazine compatible:
The feed port was designed to accept AICS and AW style magazines.
Remington 700 Trigger Interface:
With a Remington 700 trigger interface, many trigger options are available.
60° Bolt Throw:
With a 3 lug design, the bolt throw can be kept to 60 degrees, ensuring quick operation.
Battery Safety:
The firing pin can only protrude the bolt face if the lugs are locked and in battery. This safety mechanism ensures that if the bolt is not in battery, the rifle does not fire.
