Marlin 336 misfires

[ba_50]

Leverdude over at Marlinowners mentioned the spring pushed his back bolt pin down too far and made for poor firing pin hits.

After taking my bolt out, I tried to push the pin forward and it wouldn't go all the way forward, leaving a small amount of pin outside. The lower front part of the pin has been peened some.

Should I bend the spring up a little? Anyone else had this problem? Thanks.

   If your are sure that the front part of your pin has been peened, I would just buy a new firing pin and install it, before I would mess with altering the spring.   

  I'm the kind of guy who would just buy both a new spring and a new firing pin, and install them and forget it.  You can get them by a phone call to Brownells.   Life is too short, and a misfiring rifle is far too dangerous, to be fooling around with altering small parts.

 Sorry for a second reply, but before ordering any parts, I would consider the following:

  1.  Are you sure you don't have a bad box of ammo with bad (hard) primers?  I once had a box of PMC ammo, and every fourth round simply would not fire, due to bad primers.  Other boxes of the ammo fired without problem.  So, get a different box, preferably a different brand, and see if they fire OK.

  2.  Take the bolt out, and soak it with Gunscrubber, clean with brush, and then soak it in Hoppes, clean with a brush, and then soak it with WD-40, clean with a brush, to make sure that the firing pin channels and holes in the bolt are not rusted or clogged up a bit.

   3.  Take the firing pin and very very gently polish it with 400 and then 600 grit emory cloth, just to slick it up a bit.


    It is possible that one of these foregoing may solve your problem.

   Also, remember that eventually, firing pins do wear out in the ordinary course and need to be replaced

Hope this helps.

mannyrock,

I found out that when the bolt goes up, it pushes the pin up so the firing pin will go forward. I don't think the spring needs alteration. Cleaned it 3x, but there could still be dirt in the front end. If I can find something to get in the front part of the bolt to scrub it out I will try it again.
