Need some help: bolt issue

[mercdeking]

I'm adding a scope mount to my rifle (S&K in order not to damage anything) but I also didn't want to grind on my current bolt. So I bought another one and I was going to make sure it was ok. Anyways,
the replacement bolt came from Numrich aka e gunparts:
Springfield 1903 / 1903A3 Bent Bolt Assembly*|*e-GunParts.com

It's in good condition and actually looks slightly better than mine which is worn in!

At first I thought that there was something wrong with the unit when it would get stuck and I couldn't get it into the receiver. When I moved the extractor to a to face straight up the bolt would slide in with no issues but of course the extractor is now in the wrong position to allow the bolt to close.

Any way to find out why the extractor is causing an issue?

If I leave everything lined up like my other bolt then the bolt doesn't go in but my old bolt works fine. Really don't want to go with extra high rings since that isn't what I was going for.

Any help or suggestions appreciated.

Well I own a mauser and from looking at surplusrifles bolt disassembly guide I got mine apart and switched extractors from my old bolt to my new bolt and it now goes in pretty smoothly and I tested the unit with some unfired but run through my dies case and everything functioned and closed properly.

I then tried my old bolt and put the new bolts extractor on that and it would not close. So I got a funky extractor it seems since the old extractor works on both units and both units work without that new extractor.

Time for another extractor unless I can figure out what is wrong with the dimensions of the old one in order to make it work.

Ordering another extractor would probably be easier!

Still haven't managed to get my old sight base off the rifle; so far tapping hasn't gotten me anywhere except that I missed the base once but it's a good thing I was using a brass hammer since the mar was just on the surface and cleaned up good. ouch...

That old sight base is pinned to the rifle. You have to look very close sometimes to see that transverse pin, but it is there. If you have never removed one, it is very likely you will damage the base.

lets keep this in line,,,
this post is about a 1903..not a Mauser.
Mauser sight bases are high temp soldered in place, no amount of pounding will remove it, only heat from a torch,{not a propane torch} will get it loose.
second.
some skill will be needed to remove a rear sight base from a 1903, 2 pins, one in front left to right, one in the rear to keep in in line.
if you havnt done one, you will destroy the base you have, leave it alone, and find a rifle thats already messed with..
3rd.the bolt,
Gunparts bolts are junk, plain and simple. likely done without a heat sink, and warped, and were done on bolts that were not to spec in the first place,
chances are youll have to notch the receiver to clear the turned down bolt as welll,
buy high rings, and be happy.
or . look for another bolt that will work safely and smoothly in your rifle, and check locking lugs, and headspace.

I've haven't seen any pins on the rear sight base of my 1903a3; it's a remington 1903a3, ser# 41285XX. T



So far now that the peep sight assembly is removed, I see two indentations or stakings as I've found out that they are called. It seems mine is of later manufacturer so it doesn't have a set screw.

The bolt issue was from the extractor, From looking at it I can see a slight rise on it where it wasn't perfectly ground down; so it was probably some cheapo.

The bolt on the other hand seems to be fine (after changing the extractor) and is in good condition. it clears the receiver fine and closes fully. I might still keep with my old bolt until I check headspace but things look fine so far.

It will still be changing over to the scope, If I can't shoot it accurately with irons then I'm going with a scope. I can even use the scope mount to mount my eotech since that's always given me a better sight picture anyways. Boy that would look wrong though...

As Chuck said check the headspace since it is a new bolt

[Chuckindenver]

well, a 1903A3 sight is drifted from left to right, some early types have a set screw as well,
later will just be staked in place.
the fact that said rifle is a 03 or an A3 wasnt brought up, so i assumed it was a 1903..
