The MPA MUT RIfle (Micro Urban Tactical) 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 8.5″ in length.

This can take a suppressed rifle measuring up to 48″ in length and reduce the overall length to 23.5″ with the suppressor stored in the buttstock and folded/locked in an SBR Configuration.

The rifle is available as an SBR with a barrel length of 12.75″ or as a standard rifle with a barrel length of 16″ or longer.

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.
