Same quality as some of the cheap Chinese guns if you ask me.
Breach was very loose and would not tighten down enough to improve it.
Ended up making a shim for that. Trigger was the worst I have felt but polishing helped quite a bit. Swapped the spring guide from the piston to the rear to reduce it's mass. Same velocity but much less recoil. Not a bad gun for short range now.
