Hello all. Looking for a bit of advice here regarding a Ruger Mark II that I recently sort of inherited. I know the weapon fired recently then it came to me and set in the safe for a few months and prior to firing it I wanted to clean it and check it. I went to disassemble it and ran into a few problems that I haven't found an answer to.
I think that the root of all the issues with this weapon is that the barrel and lower are slightly misaligning. I worked for several hours getting the thing apart, cleaned, and then put back together. Getting it apart the first time was a real job which I wrote off to it just not having been cleaned recently and sitting for so long, but now I think it was due to the misalignment problem. I discovered the problem when I reassembled the weapon. The bolt seems to be binding up and torquing the trigger and hammer assemblies so that they bind up as well. This binding seems to be being caused by a misalignment of the lower and the barrel. Its the only thing that I can come up with after spending the night working on getting it apart, back together and having the bolt bind up, working to get it apart again, reassembling and it magically worked, disassembling to see what was going on a bit and then reassembling and it binding up. It was at this point that I noticed the front of the lower wasn't exactly straight like I thought it should be across the barrel.
As it stands now the main spring housing will not freely come out. It is going to take a lot of finessing again or some tool working to try and force it. Looking at the firearm and the tools marks already on it I would say this has been a recurring problem in the past. Also, the bolt will only slide about half of an inch rearward and then stops.
This shows how far the main spring housing will come out with a bit of work before it binds up completely.
This one shows the max the bolt will travel before it binds up and stops.
This one is sort of hard to see the misalignment that I noticed but the left side of the lower (in the picture) is slightly further back than the right side. I would say there is about a little over a 1/16th of an inch difference.
As I said above, apparently this has been an issue for some time judging but the tool marks scarring the weapon. I am just wondering if it is something that is fixable or not or if I am way off on what I think is wrong here.
Thanks in advance!
