Hey all,
I have a pws mk109 300 blk pistol that I've been trying to get to work, and would appreciate some tips before it has to go back to the manufacturer.
9 inch barrel, piston system, carbine length tube with carbine spring and h1 buffer.
tried both 150 gr fiocchi and 110 gr hornady black vmax, so this isnt a subsonic issue.
I can see what looks like residue from some gas leakage at the 9 o'clock next to the gas adjustment knob, and residue all along the sides of the charging handle after shooting.
With the 150 gr, it will fire, but not eject the casing, instead just bumping the bcg back and then returning to battery with an empty casing chambered. With the 110's it will eject the empty casing, but will not chamber a new round.
