Can someone post a picture or two showing a side by side comparison of the bolts. I got the scope mount mounted, just need to see what the difference in the bolts is. is it just a thinner bolt handle to clear the scope bell on the M-73, or is it ground/cut for clearance.
thanks in advance
Not just thinner, reshaped in several dimensions.
Side by side of A4 vs Remington A3
The A4 handle was basically forged to a different shape then finished by grinding/polishing the handle.

thanks all for the pictures. I was wondering if I could just thin the handle on a regular 03a3 bolt but obviously the are forged/bent differently. got my 03a3 A4 Repro wearing a Weaver K-4 with higher rings right now till I figure out how/what Im gonna do for the bent bolt so I can mount the M-73 repro scope.
You can see how much closer to the centerline of the bolt that the root of the bolt handle is. That is why there is a cutout in the stock for the 03A4 bolt.
Noonanda..you can probably modify a standard bolt to provide enough clearance for use with a Weaver 330 series or even a Lyman Alaskan. Exactly duplicating or even coming close to the profile of an original is fairly challenging piece of work.
Does anyone know of someone that is capable of doing of altering an A3 bolt to A4 configuration? Thanks, Rick
You could buy a bolt already modified for scope use for less money than you would spend having someone ( a SKILLED someone) alter yours.Quote:

chuck moline at molinenorski@msn.com aka chuckindenver on the forums can do the a4 bolt conversions plus cut the gunstock for bolt clearance
or just put it in a vise, grind with an angle grider, heat it with a torch and beat it with a large hammer right? lol...hey after all, anyone can do it..
just had to toss that in. guys think its an easy task.
thats what numrich does..they grind em, heat em, and beat em..and send em to you..and yea, they work great...NOT.

Reminds me of the forging blocks I have seen in the past for re-working straight mauser bolt handles.
I bought one of those, and that's what it looks like. I had no idea.Quote:

Plus, you then have to make a cut out in the stock. I bought a scant stock, but it's USGI and I don't think I want to ruin it. I think buying a commercial C stock would probably be the way to go. But I don't really have extra money right now. Maybe some day. I would like to figure out how to do it properly if I ever do get the money to though. But there are a lot of things I'd "LIKE" to do. Hehhehehe What mount did you use? That's another thing, I'm not going to drill and tap my receiver of course, and now I don't really see those S&K mounts for sale any longer. Hmmmmm.....
I just picked up a genuine 03A4 stock, well used but solid (SA cartouche in a box on the left side of the stock, serif "P" in a circle on pistol grip - no other markings), and have an A4 bolt that looks correct and very much like your pictures in the mail. But although he had owned if for a number of years as a spare, complete bolt for his personal 03A4 the seller said he could not find any markings on it, and thus sold it as a possible repro. Finish and wear looks close to new. Is it possible that a correct A4 bolt body got out of the factory without markings? (I'm mounting an S&K scope mount setup just to test accuracy on a 1903 rather than relying on old eyes! Originality is not absolutely necessary - not cutting up the original rifle or stock is.)
In looking at the bolt pictures he posted, I noticed that his 03A4 rifle had what appeared to be a slight cutout in the reciever metal, directly beneath the bolt handle, and in line with the stock cut out. Were the issue M1903A4 recievers themselves relieved for the bolt handle? Is this necessary or useful? CC
M1903A4's do have a slight relief cut in the receiver just under the root of the bolt handle.Quote:

The machine marks on Remington Bolt sleeves also have a very distinctive pattern.
Naturally if a rifle had been refinished and many many A4's were at some point some of the identying details may be obscured.

I have an original A4 bolt in my clone (A3 receiver). Although the bolt does seem to close all the way, headspace is fine, I can see where the sharp edge of the receiver has made a small mark on the underside of the handle. So I guess the relief is necessary. I plan on taking a file to mine. :DQuote:

That hurts to look at. :surrender:
At the last Reno gun show a guy had two genuine A4 bolts. One was new unissued @ $400 the other was used @$350. Pretty pricy but the first I had seen in a long time.
Heres a bunch more not drill rifles this time :) :Quote:

Chuck can do you a great job and is trusted by many here - CMP and others do similar work (sometimes at greater expense) and once in a while a real 03A4 bolt shows up on eBay or at a local gunshow. Good Luck with the rifle. CC
