I have a Hahn bottom loader that I've had since late 2005. When I first received it, I had a gunsmith shim the ejector because the gun was malfunctioning constantly because of the slop in the ejector. After the shim, it ran great for several years and probably 1,500 plus rounds. Recently it started to puke to the point it couldn't fire more than one round. On some advice, I tweaked the ejector until it BARLEY cleared the bolt. I tested it yesterday and it seems to be running 100%. I was suprised at how much I had to tweak the ejector to get it tight to the bolt. There should be a picture below of the now working ejector. Has anyone else had to tweak their's so much? (Setup is a RRA Upper with ramped bolt and Colt SMG magazines)
