JP Enterprises recently introduced a new bolt-action rifle, the MR-19. Moreover, the MR-19 results from a collaborative project with Ultimatum Precision and Proof Research, both widely known in the precision rifle market.

JP utilizes its new APAC Chassis System for the MR-19. Billed as a “next generation” chassis, the APAC is fully ambidextrous and fully adjustable. Further, U.S. Army sniper instructor and precision rifle competitor Brian Whalen designed the chassis.

JP Enterprises MR-19 Features

The rifle also incorporates the Deadline short action from Ultimatum Precision. This release comes as the culmination of a very productive year of coordination and co-development with Ultimatum, whose Deadline action has become one of the most popular choices in the precision rifle field, according to JP.

Finally, the MR-19 features a custom-counted, 26-inch Proof Research barrel. Proof has blown up in the precision game of late, and JP began offering a limited selection of Proof barrels in custom gas gun builds last year, a first for JP.

JP describes the MR-19 as a “turnkey precision rifle package.” The rifle includes standard upgrades including a Magpul MIAD pistol grip, JP Thermal Dissipator heat sink, full-length Arca-Swiss adapter, and custom-cut foam designed to fit the Pelican iM3200 Storm long case. Further, standard caliber offerings include 6mm and 6.5 Creedmoor with right- and left-handed actions available.

JP’s Bolt-Gun History

While most folks know JP for its gas guns, the MR-19 represents the continuation of a 12-year foray into manual rifle development, according to JP. The company’s original bolt-action, the MOR-07, debuted in 20017, while the MR-10 launched in 2010. Now the company strives to adapt the ergonomics and quality of its gas guns into the manual rifle platform, according to JP.

“Bolt guns are not what people immediately think of when they hear ‘JP’ but we’re no stranger to this market,” says JP founder and head of product development, John Paul. “I really view it as taking what makes our gas guns work so well and bringing that to the bolt gun world. As happy as I am with the viability of our gas guns, the bolt guns will always have a place in precision shooting. The MR-19 makes that place as competitive as it can be.”

The MR-19 retails for $4,999 and is available for order now. For more information, visit
