I bought this rifle back in February and I never thought to take apart the bolt to check out the firing pin assembly when I first brought it home, I was too excited to go out and shoot it. I cleaned off some of the excess factory oil. lubed the bolt, receiver, and put a drop or two down the firing pin hole on the bolt face. Needless to say, I won't forget to pull out the firing pin assembly to inspect it next time I buy a new rifle, and here's why:

About 4 weeks or so after I bought the rifle, it started to misfire, it was striking primers very lightly and wouldn't set them off. I figured that I set the primers too deep by accident... so I tried new primer depths but I couldn't find one that would allow the rifle to fire. After that happened, I took the rifle home and pulled the firing pin assembly out of the bolt and much to my amazement, this is what I had found:

I was stunned to find everything so badly covered in rust and corrosion. The firing pin itself was pitted as the rust started to eat through it!! I figured I could clean it up with my new Dremel and decided to see how clean and polished I could make it. I first coated everything with WD-40 and let it soak for awhile. Then I used the Dremel with different stainless steel brush attachments to knock off the corrosion, then took polishing compound with several felt attachments to make it shine. This worked out great!! I polished everything, cleaned out the entire inside of the bolt and oiled it all with Rem Oil after I was done. After re-assembling the bolt, I installed it back into my rifle and I was amazed at how much smoother and easier the bolt lift was and how much more clean the trigger felt when it broke. This is what everything looked like after cleaning and polishing:

I would guess that they would have oiled that area prior to boxing it up at the factory, but maybe it sat for too long before I bought it and it rusted...I have no idea what could have happened but it definitely sat rusty for awhile, the firing pin was pitted in a bunch of places.....

I always strip down the bolts on everything and give the going over. I chuck the firing pins in a drill to do the polishing, and use wet/dry sandpaper. Flutes are done by hand with the paper if they have them.

Is there a reason you felt the OP should be questioned?

Take a look at the front portion of the firing pin in front of the spring, you can still see gray areas that are probably deeper pits left by the rust. If a new firing pin assembly came with those marks I'd be even more upset...

Yes I'm being legit....it's the same assembly, a Dremel with the right attachments and a lot of time spent cleaning and polishing gives you results like this....why are you doubting me? haha

If you zoom your browser wayyyy in, you can see between the coils in the spring and the pitted firing pin becomes very noticeable... check it out

A blast cabinet and wire wheel would clean it up in a couple minutes. But with a dremel, damn. Nice job!



I've never seen one that looked like that and I take apart every single one that comes in the door. I've only see a few hundred, but none looked bad enough to need cleaning.

Yours looks like it sat in salt water. I'd replace it. New firing pins are cheap, and new assemblies arent too bad either. I know they look great right now, but theyll be prone to rusting again, and seeing rust that bad turns me off of any part unless it is to be re-finished.
 
Re: New Rem 700: Rusty Firing Pin Assembly...PICS!

that was in a remington you bought thats was brand new? i would have given rem service a call if thats the case.

how easy is it to take the firing pin out of the bolt?
 
Re: New Rem 700: Rusty Firing Pin Assembly...PICS!

I had the rifle for about 4 weeks before I started having the light primer strike issue. Then I tore the bolt assembly apart to see what was wrong. In the future, I'll be sure to break down the bolt assembly the first day I bring the rifle home... lesson learned I guess
