    Hey guys, do any of you know where to get an after market firing pin for the mvp in 223? Mine seems to be to soft, because when shooting it, if at all in repetition(like 15-20 rounds in about 5 to 10 minutes), the end will swell, and not allow the pin to pass through the bolt face. I am using reloads, but not particularly hot loadings. Has anyone else had this exact problem? I have seen some other posts that are similar, but not the same. When this problem happens, I am forced to disassemble the bolt, and re-size it with emry cloth or sand paper, which is not exactly apealy get to me both for time's sake, and the gun's. Any feedback would be greatly appreciated!

    Thanks!

    Is the firing pin deforming? If it is I would contact mossberg.

    Yes, it is deforming by swelling, and thank you for the reply! I have sent mossberg a message on their contact list, but have not received a reply yet. My bet is that they will want me to send them the whole rifle, which is not an attractive option for me based on their fixing time, and since this is the time of year that I use this rifle the most. This is why I am looking for an after market firing pin, maybe a lighter one to if at all possible. Any help is welcomed and appriciated!

    Thank you

    You might be able to get a local machine shop to try to heat treat it. The problem with that would be they wouldn't know what material it is so they wouldn't know exactly what to do to it. Life will be easier with these rifles when parts are made available.

    Or you could get a local machine shop to make you a new one and then heat treat that one so you're 100%

    Or you could talk to forum members Robert Lynch , Mbacon, X-ring Accuracy, Tony Rumore about turning you a one off. Maybe from something like EDT 150 steel.

    Just something to think about.

    Hi guys,

    Mike and I just talked about this last night. We are thinking about doing some light weight pin assembly's out of titanium.

    I'm in. Especially if it helps with military primers, although that seems unlikely(?).

    Pastry, that is a great question. I will get back to you on that one.

    I'd guess not because lighter weight generally won't improve light striking. Maybe somebody else knows better.

    Lighter pin just to reduce mass and jump when fired, but the spring would be the same. I am going to find out. It would be a good test to do.

    I'd be in for a spare anyway, and fixing the light strikes would be gravy. Maybe a new spring would sweeten the pot, hint hint. :) I know I've mentioned before that a small parts kit would be huge. Let me know if you need a test bed. I get unacceptable levels of FtFire malfunctions with mil spec ammo. Like 80% range.

    Rob, I've had absolutely zero problems with my firing pins but I'm in for both :D some titanium ones for the varmint rigs and some steel ones, preferably with extra mass, for the bush rifles ;)

    I agree.

    It's common in the AR world for folks to like having spare parts kits whether they need them or not. IMO that concept has bled over to other guns which I think is good for the aftermarket as well as peace of mind for the the consumer. We just shoot more nowadays than before.
    I will likely never need parts for my MVP but my descendants might booger something up so I'll buy.

    If y'all ever get a firing pin designed and made for the MVP in 7.62, I'd be interested as well. Like the other fella said, I keep spares on everything I can. Never know when something is going to go belly up on you.

    Best,
    Grumpy
