Since the M84 was to replace those M81/82 scopes coming out of service, only a small number had been produced by the end of WW2. Like the elevation knob, each click moves the post 1 m.o.a. It has a total windage range of 100 m.o.a. and numbers at each hundred yard increment. The elevation scale starts at zero yards and elevates to 900 yards with line marks every 50 yd. for each click, which are usually felt rather than heard. The finger adjustable knob gives 1 m.o.a. of vertical movement of the post for one complete revolution of the drum. The elevation dial has 32 threads per inch which provides 40 m.o.a. In my shooting with it, the top of the post appears to subtend 3 m.o.a., or 3 in. and it was sealed with rubber gaskets to keep out moisture. 870 in., length with rubber eye-piece and sunshade extended is 13.2 in., the reticle is a post with horizontal cross-wire, eye relief is 5 in. It has a universal focus, field of view is 27 feet at 100 yd, diameter is. For unknown reasons those scopes were rejected and the T134 adopted in April '45 as the M84. As a 2.2 X conventional design (T134) very similar to the M82, it was to compete in field tests against 3 X and 4.5 X designs in June of '45. opens the history on the M84 in early 1945. Chapter 4, Semi-Automatic Sniping System, The M1 Garand, goes into considerable detail on the history of the M1C, M1D and their scope and mount development programs. I found this book at the library while researching info. Peter Senich provided the most detailed information on these scopes that I have found in his book LIMITED WAR SNIPING, Paladin Press, 1977.
The M84 scope replaced the M81 and M82 and was standard issue in April 1945. Numerical graduation marks had a value of two m.o.a. The M81 had a cross-wire reticle and the M82 a tapered post, otherwise they were identical.The reticle was internally adjustable for windage and elevation in one minute of angle clicks. This lists specs on the M81 and M82 scopes as follows:īoth were Lyman Alaskan scopes produced for the military.
Rifles, Cal.30, M1, M1C and M1D (Sniper's). Not much out there! A friend loaned me his 1947 copy of War Department Technical Manual TM9-1275 Ordnance Maintenance, U.S. Fulton Armory FAQ: On the M1D and M84 On the M1D and M84 by Bruce JacksonĪfter getting a beautiful M1D with all accessories from the CMP last year, I went in search of information on the M84.
