For sale: a like-new Maruyama MPIX, only tested, but not used in fields.
It comes with 1 magazine. The rotor problem has been fixed with a guillotine rotor; furthermore, it features a 4UAD nub, a CNC 1913 adapter for a cool custom stock, a CNC magwell, and a CNC trigger. Unfortunately, the plastic arm/lever of the original trigger has broken off, and it has an AIM-O SRO Style Red Dot.
Unfortunately, I am too busy going out with the MP IX at the moment, so I think it is a shame to keep it.
