1903a3 bolt compared to 1903A4 sniper bolt

[noonanda]

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.

FWIW,

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.
