1903 Springfield National Match Question - COCKING PIECE

[pete-z]

Question:
The headless cocking piece on a nm rifle bolt is short by about 1/4" to make it fire. Somehow the wrong piece got into this rifle.

Upon investigation, i see that there are at least 3 headless cocking pieces. The right one for this rifle appears to be the longest one. The other two are shorter and different lengths from each other.

Is there a designation for this headless cocking piece? How would i describe it when looking for one?

Thanks

I am not aware of the designation for the headless firing pin assembly you seek. I suggest that you describe it by the length measurement of the exposed rod. For a standard Natiional Match headless firing pin assembly, the exposed rod is the same length as a standard service rifle firing pin assembly.

The shorter headless firing pin assemblys are for the Cal..22 M1922 and M1922M1 rifles. As can be seen from the scale drawings of the cal..22 parts on pages 238 and 239 of the book "The '03 Springfield rifles' Era", the Mi922 assembly is slightly shorter than is that for the M1922M1. Both, of course, are shorter than the Cal..30 assemblys.

As to the NM rifles, the headless firing pin assemblies with reversed safety locks were optional from 1920 until made standard in 1924 (page 81 of the book referenced above).
They were abandoned in 1930 except that the headed assemblies for that year were cut for the reversed safety locks (pages 96, 97).

The headed NM firing pin assemblies from 1930 on, by the way, were made of chrome vanadium steel and were marked CV. The drawing number was B147183 (page 236).

I checked the measurement against a standard cocking piece and it is about 1/4"
short.

The standard cocfking piece does fire the rifle.

I know what I need but didn't know if there was a part # or description. I suppose there is a part # someplace but
I can describe it as that would be simpler.

Still need one.

Thanks

The rifle is a 1924.

I learned something again.

issues with headless cocking rods that iv seen,...
most are to be used with the reverse safety , so firing with a standard safety will likely slow the lock time,
also, said cocking rod is to be used with a heavy spring...that spring is real tough to find, so
i used a Wolf spring Model 70 spring. works like a charm...but is a bit tough to open the bolt with a spring thats tough enough to set off a live round,
thats a trade off.
these were some of the issues they had with the headless cocking rod.
and the big safety issue...the flaired knob was used for safety, no so much as a grab handle...to deflect hot gas away from the shooters eyes in case of a failure...
