Default What is the difference?

Between a 1903 and a 1903A3 Springfield bolt? I see them listed as fitting either gun, but ............

I need one for a 1903A3 build and don't want to start with the wrong part. I just need the bolt body.

Thanks,
George

Subject to the limits of headspace '03 and 03-A3 bolts are generally interchangeable. There are numerous minor variations in 03 bolts since the rifle was made for such a long period of time; at different arsenals and contractors.

Since you need a bolt for an A3 the process of finding a replacement should be simpler.

There were two contractors for the A3 - Remington and LC Smith Corona Typewriter. It would be nice but not essential if the bolt matched the rifles original contractor. New spare parts A3 bolts still are available. Check eBay, the parts dealers and gunshows.

Regards,

Jim

Notice the cut on the A3 bolt body around the safety lug: http://www.vishooter.net/m1903/rem_bolts.jpg VISHOOTER's site is a great source for M1903 and M1903A3 info. It's the best source for manufacturing date info. Most other sites are full of errors.

Thanks.

Springfield Model 1903 and Model '03-A3 rifles use the same bolt. However, by the time the Model '03-A3 went into production, the Model 1903 bolt incorporated a number of manufacturing shortcuts to reduce cost and speed production. Most noticeable were the shallow circumferential grooves in the bolt body around the bolt handle, safety lug, and locking lugs and use of a stamped extractor collar.

Hope this helps. Happy New Year!

J.B.

Default 1903 Vs 1903A3 Bolts

Hello,

I have tried to seach around a bit with poor results. Can anybody tell me the differences to look for between 03 and 03A3 bolts?

Thanks,

Pat

The basic difference is the 1903 bolt has a straight handle, meaning it is 90 deg to the bolt body and is contoured downward. The 03A3 starts off 90 deg to the bolt body and than curves down and back.
I will try and get a picture up.

The bolt body on a 1903A3 is under cut.
