My first M1917 rifle

[Sapper740]

You can easily tell if the front sight is a .060" or a .090" by measuring its height above the center line of the bore. The 11 various front sight's heights will be between .985" and 1.135" so a .060 stamped sight will be 1.060" above the center line of the bore and a .090 will be 1.090". You may wonder why .060 and .985 don't add up to 1.060". That is because the first two sight heights are -.015" and 0". Remington's production started in 10/1917 and continued until 12/1918 with a total production of almost 586,000 rifles. Your barrel is original since M1917 replacement barrels would be stamped either HS for High Standard or J.A. for Johnson Automatic and would be parkerized. All this information can be found in Charles Stratton's British Enfield Rifles Volume 4.
