I have what appears to be a Rem QC issue with my new 3gun VM. One of the cylinders that houses the pistons on the gas block appears to have machined improperly and will not let the piston move within the cylinder. Naturally in my one and only range trip before discovering this, the gun wouldn't cycle to save it's life. I sent it back to Remington for repair so we'll see. I guess I've been lucky but this was my first time ever having an issue with a gun out of the box.
