Q. on replacing Rem 700 firing pin

[The Baron]

I am looking for instructions on how to remove the firing pin head/head pin and install a new firing pin and spring into a Rem 700 SA. Of course, I'm looking for instructions on how to put it back together afterward. Do I need a special tool? Thanks!

You need to be able to compress the spring to the point that the pin through the cocking piece is exposed, and can be driven out. Once it is out, the firing pin may or may not be free from the cocking piece; sometimes the fit is rather snug. The firing pin MUST be controlled - if not, it can be projected with considerable force, and is pointy on the end.
Reassemble in reverse order.
It is really worthwhile to use a tool to control the compression of the spring, and keep the firing pin under control. These need not be elaborate. I made a tool from a piece of barstock with two 1/2x13 nuts welded to it. The bolt sleeve screws into one nut. A 1/2x13 bolt screws into the other. It is drilled out to suround the firing pin. When the bolt is screwed in, the firing pin is pressed back, and the cocking piece protrudes from the bolt sleeve. There are tubular versions of this sort of tool.
Brownells sells the tools for this job.
When you reassemble, make sure that the pin is properly and smoothly reinstalled. The holes in the firing pin and cocking piece need to line up exactly. If it is damaged, and were to shear, the rifle could fire.

I use the bolt body as the tool to compress the firing pin spring...

I remove the firing pin assembly, drop a piece of aluminum tubing (a piece of arrow shaft) about 3/4's of an inch long into the bolt body and screw the firing pin assembly back into the bolt... the tubing is small enough to go to the front and hold the firing pin back....

then remove the cocking piece retaining pin and cocking piece... figure it out from there....

If you put the bolt in some soft jaws in the vice and pull back the firing pin where the trigger mechanism engages the pin, with something non marring like a piece of brass.
A slot will be exposed on the very back of the firing pin assembly. I put a thin washer in this slot. This will hold the pin back.
Now you can screw the pin out of the bolt.
Now you can recompress the spring and remove the washer and let the spring tension off and the pin comes apart.
Reverse procedure to put back together.
Use proper eye protection when playing with compressed springs.
Also I may not understand your question.

Thats an awesome idea. Never thought about that. I just bought a took from Brownells that works pretty good as well.
