The gun shows no obvious signs of having been worked on before and overall is well worn which makes me think it did work well at one time.

Why was that a good idea? And what d'you have to do NOW to figure out which? Or not.ĭoes seem to have been jumped onto without much detective work beforehand, though. What you just did might be a positive step. Might there be any OTHER modifications to this truant puppy? If all that was 'don't care', we'd have had reliable gas-operation 200 years earlier. Not to mention short stroke and long, the mass of the moving parts, WHERE the peak energy is contributed in time, to what transferred, and where consumed. How much, how ignited, and with what burn-rate? Barrel length on EACH side of a gas port can matter. All parts seem to move smoothly but it still will not eject the brass! Any ideas?Ammunition has a propellant. I have brushed the chamber out well, removed the bolt and polished the ejector pin bore and made sure the ejector had plenty of travel.

I also put a larger diagonal cut into the gas block plug (this is not the same as US issue M1 carbine gas system). Then I drilled the gas port out with next size up #drill, tapped the hole in the gas block 1/4-28 and added a ball bearing under the 1/4-28 set screw to prevent the gas from leaking but allowing the piston to move freely. At first I figured it was under gassed so I dismantled the gas block piston assembly and drilled through it to get to the gas port in the barrel.

Not a stove pipe, the case is still parallel to the bore. When fired, the empty case gets extracted but not ejected and get trapped between the bolt face and cut out in the receiver. I have this Universal M1 carbine type pistol - the Enforcer, that refuses to eject properly.
