The overall premise of this rifle is a custom built, application specific rifle. Due to the significantly reduced weight of the chassis, and the accuracy capabilities, this rifle has tremendous long range hunting capabilities. The customer chooses his caliber and chamber, along with the length and contour of the barrel. These choices will be determined by the application for the rifle.

If you plan on packing the rifle for extended ranges on foot, then a lighter contour would be appropriate. However, if plans include using a muzzle brake or suppressor, the muzzle diameter needs to be large enough to provide a shoulder for the “end of barrel” device to attach and locate.

If you are focused more on velocity and extended thermal stability of the barrel, then a longer, heavier contour may be appropriate.

Refer to the contour chart on the “Precision Rifle Barrels” page on our website.

All chassis and barrels are cerakoted, and we provide a multitude of colors and patterns. Solid colors are included. Custom patterns have a +$150 upcharge.

The length of pull and cheek riser position are adjustable and locked in position with a series of set screws that are embedded into the buttstock body. This is the same system we use on our standard BA chassis, but without the thumb wheels.

The adjustable monopod can be added to this chassis, along with the bag rider plate.

Trigger type and pull are also important considerations. We offer either the Rifle Basix L1 (1.5-4lbs) and the LV1 (8 oz to 2 lbs) as our standard triggers. Just pick the trigger pull you want. We also can provide the rifle with other aftermarket triggers. Timney, Jewel, Huber and others. Just let us know if you have a preference other than Rifle Basix. Triggers other than our standard will include an upcharge depending on the trigger.

On caliber selection, if your choice is not shown above, contact MPA. If a chamber reamer is available, we can create the rifle. Twist rates depend on the caliber and projectile weight.

The spigot mount is an accessory mentioned above is designed to be inserted in the front of the chassis to provide an extended distance between the front bipod and the rear support. Simply insert the spigot into the chassis and attach with (2) Flat Head Cap Screws. Then move the pic rail to the spigot.

For those who would prefer a sling stud instead of the picatinny rail, just let us know.

At the time of order, please choose your caliber, barrel length, contour, trigger type/pull weight and color.

Bipod is not included.
