I bought a MKI a bit ago and am having a few issues. The sear isn't resetting when it's fired. I can cock it and dry fire it all day long. But if I simulate shooting by not releasing the trigger after a dry fire and racking the bolt again the sear wont engage the hammer. After releasing the trigger, I can wiggle it a hair forward, and I'll hear the sear click into the hammer, and it will fire.
I've found a few potential things that could be causing this.
#1. Sear spring stop pin is bent.
#2. Hammer pivot pin is bent (have a feeling this is the cause of my problems as I feel it isn't allowing the disconnector to freely move around the bushing or is holding the hammer a bit off)
I can find the sear spring stop pin all over the net. But I cannot find the hammer pivot pin anywhere. Will the MKII pin work in a MKI? I see it isn't a plain dowel, but has a head on it. I haven't looked it up yet, but while replacing pins I figure I may as well go ahead and replace the sear pivot pin too. Can it be found online anywhere? And, it there a chart somewhere showing compatability between MKI and MKII/MKIII parts?
Any other ideas to fix the problem would be appreciated too. I've not done a total dissassembly on this gun before, but I think I'm capable of it if need be.
