MasterPiece Arms Introduces Four New Technology Developments

MPA rolls out the Trinity Rail System, Bag Rider with Flush Cup, Data Card Holder and BA Lite Night Vision Bridge System designed to improve a shooter’s performance in a Precision Rifle Series event.

Comer, Ga.- (October 2016)MasterPiece Arms (MPA), manufacturers of the MPA BA Rifles, Chassis Systems, Defender Pistols and Carbines, Suppressors and MPAR Rifles, is pleased to introduce four new technology developments that will improve shooter performance in Precision Rifle Series (PRS) events. These new innovations are theMPA Trinity Rail System, the MPA Bag Rider with Flush Cup, the MPA Data Card Holderand the BA Lite Night Vision Bridge System.

The MPA Trinity Rail System is designed to be used on any MPA Chassis, including the MPA BA Chassis, MPA Comp Chassis and MPA BA Lite Chassis, providing an alternate location for positioning a bipod. This is an ideal accessory for rifles used in competitions similar to PRS events. This system allows shooters to adjust their bipod location so they can have a stable shooting position on short or limited surfaces, such as a 55-gallon drum, spools or rock outcroppings. The MPA Trinity Rail attaches to the two slots that run the full-length of the bottom of the fore-end ofthe chassis body. The system includes the Trinity Rail Base, Short Bipod Picatinny Rail, (4) SHCS and (4) M-lok nuts. The system weighs 1 pound and is designed for quick and easy installation and removal.

The MPA Bag Rider with Flush Cup, weighing in at 1 pound, is based on an idea from Dave Preston, winner of the 2015 PRS. The purpose of the Bag Rider is to allow a consistent management of recoil when using a rear bag, while the Flush Cup, as conceived by Preston, is to be used when a sling is worn to provide support for the rifle during certain positional stances. Having the Flush Cup use the rear connection point on the bottom of the rifle allows the rifle to pull downward, as compared to side positioned flush cups which can trend the rifle laterally. The Bag Rider attaches to the user’s MPA BA Chassis, Comp Chassis or BA Lite Chassis through the threaded three-hole pattern in the bottom of the buttstock body. MSRP $29.99.

The third innovation from MPA is the MPA Data Card Holder. This new system is designed to be used on any MPA full size chassis to provide a quick and effective method of viewing the shooter’s DOPE for target distances while keeping his cheek welded to the cheek riser. The Data Card has a surface similar to a dry erase board and is compatible with grease pens, dry erase pens or a Crayola® Washable Marker. When it is time to replace the data, simply wipe off the markings with a cloth or paper towel. To ensure that data isn’t accidentally erased, the shooter also has the option of putting painter’s tape on the card to write the data on and simply removing the tape when the stage or shooting session is completed.

The Data Card can be oriented top to bottom or left to right, giving the shooter multiple options for card placement, as well as the ability to write the DOPE on the card while not attached to the rifle. MSRP $49.99.

The BA Lite Night Vision Bridge System is designed for use primarily with the BA Lite Chassis, but can also attach to MPA’s standard BA Chassis for special applications. More information on this item, along with availability, will be posted on within six to eight weeks.
