The MPA BA CSR Rifle (Compact Suppressor Ready) is a purpose driven rifle designed to be used when an ultra compact platform with a minimal stored footprint is required while achieving sub 1/2 MOA accuracy.

The specially designed FOLDING buttstock can store a suppressor up to 1.5″ in diameter (1.570″) and 9.5″ in length.

This can take a suppressed rifle measuring up to 48″ in length and reduce the overall length to 27″ with the suppressor stored in the buttstock and folded/locked.

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 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.

Bipod and Suppressor are not included.
