M1903A1 Rear Sight Slide/Slide Cap Questions

[DeputyBill]

Gentleman,
My questions pertain primarily to the Remington-made rear sight slide & slide cap (first variation*):
1) Do we know if these were typically reserved for M1903A1 rifles?
2) Was there a standard peep size used?

Thank you!

If they are R-marked, they were used on Remington M1903s. Remington M1903s were not M1903A1s. They lacked the Type C full pistol grip stock. If they were made as spare parts, they would have been used on any M1903 needing them.

Thanks Rick!

I wonder what Lt. Col. Brophy is referring to on p. 195 when he refers to "The WW II Model 1903A1 rear sight leaf by Remington..."

I understand Remington did not produce 1903A1 rifles.
So, I guess the question becomes:
Why did Remington produce these to Model 1903A1 specifications?
Anyone?

The Remington Model 1903 rear sight, for the most part, was produced to the same specifications as the last Model 1903 rear sight produced at Rock Island Arsenal.

Brophy referred to a rear sight having no 2850-yard sighting notch as a Model 1903A1 rear sight. But, the sighting notch was eliminated during WWI, long before the Model 1903A1 rifle was adopted. Brophy's reference is misleading.

Hope this helps.

Now, it makes sense!
Thanks, John.
I was getting hung up on that oft-controversial term & your explanation clarified it completely.
