M40A1 Barrel contours. Need help!!!!

[USMCHC]

Hello,
I'm new to the board and express my salutations. I belong to the United States Marine Corps Historical Company and I am putting together,attempting to!!) historically accurate sniper rifles for display and demonstration. I was wondering what are the barrel contours for the M40A1. I know the barrel length is 24" but do not know the diameter near the receiver nor the muzzle diameter. Any help would be most appreciated.

Regards,
Micheal Osborne

IIRC, 1.200" for 4" then tapers to .900"

I would recommend getting hold of Eric at GA Precision. He is a former RTE shop head and has done a number of true to spec M40A1 and A3 builds.
