i have been looking to find a new firing pin spring for my Interarms mark x .308 I have look at several site but dont see anything on a firing pin spring. Is there a good place to look for Interarms mark x parts.
Or does it take the same firing pin spring as a Mauser 98? I’m looking because a few years back I had a new one put in and now when you open the bolt you darn near need a breaker bar to do it.
It was never like that before. I have heard that people will put in what I think is a spring made by wolf which is a little bit longer and stiffer than the stock spring so I’m thinking that this is the case with mine. so do I take this spring out and cut it down or would it be better to just buy a stock replacement spring that is the correct length? If so where to get and again would it be the same as a Mauser 98 spring.

I had a Mark X in 22-250 with a PO Ackley stamped barrel on it that would shoot a ragged hole at 100 yards, should have never sold it. I improved the trigger using standard Mauser 98 parts if I recall correctly. I was told that all the workings were from a 98 design aside from some safeties. I never replaced the part you are asking about so......... Hopefully my advice is worth at least what you paid for it, lol.

Yes it is. It was hard to open first thing after the install of new spring I just went with it but now I want to do something about it. I’ve been told of this happening to others because they used a really stiff spring which is a little longer. The research I have done shows there is several different spring poundage as in 22,24,26
I get the idea that stock is less than 22lbs. I plan on buying a Mauser 98 stock firing spring or shorten this one I have, first I need to know how long the stock spring is so I don’t trim it to short.

I'd ask @AndyinEverson to move this to the gunsmithing section and summon @Velzey to boot..
