Gen 2 MPX Carbine purchased new by me in Sept 2018. This was my match gun for the last year. Gun was recently sent back to Sig on Sep 2, 2019 to repair a failed bolt carrier group. Sig replaced the bolt carrier and recoil assembly with what appears to me to be a very different design than what I have in any of the other MPXs that I've owned. Before sending the gun in, I stripped it down to the bone stock configuration.
Again, this gun has just been returned from the factory where is was gone over and broken parts replaced. The gun is in a bone stock configuration with the folding stock.
Ships in the factory box with all the miscellaneous stuff Sig sends with the gun, including one 30 round mag. Additional mags available.
