The M1C was an M1 Garand with a telescopic sight, using a mounting system developed by the Griffin & Howe company of New York. It utilized a rail pinned and screwed to the left side of the receiver, coupled with a quick-release scope on top. The rails had to be installed prior to heat treating the receivers, which had the unfortunately consequence of preventing rifles form being chosen for sniper conversion based on their mechanical accuracy. Instead, accuracy would be tested only after rifles were complete, leading to a 60% rejection rate. The scope was offset to the left of the receiver so as not to interfere with the Garand’s clip loading, and issued with a leather cheek pad to give the shooter’s cheek weld a matching offset to the left. The scope used with the M1C was the M73B1, later replaced with the M81 and M82 scopes - all military versions of the 2.5x Lyman Alaskan hunting scope (which was a very good piece of equipment despite its low magnification) The M1C was adopted in 1944, but production and quality control delays would prevent it from seeing any action in WWII. It was in use during the Korean War, however, before being replaced by the M1D. http://www.patreon.com/ForgottenWeapons Related: Japanese Type 97 Sniper: https://www.youtube.com/watch?v=LvoeQvHbCyc US WWI Sniper Rifles: https://www.youtube.com/watch?v=-dWICTS0g-E Mosin Nagant M91/30 PU Sniper: https://www.youtube.com/watch?v=OFA5U5FwJbo M3 Infrared Sniper Carbine: https://www.youtube.com/watch?v=BvfABFaiBVo ZF41 Scout Scope: https://www.youtube.com/watch?v=2oNTKnYMfI8 2 Gun Action Match - WWII Snipers: https://www.youtube.com/watch?v=kUPOD99urCE M1D Sniper Garand: https://www.youtube.com/watch?v=eqcMwiKfxb8 MC-1952 Sniper Garand: https://www.youtube.com/watch?v=DxsQShvfmMo M1903A4 Sniper Rifles: https://www.youtube.com/watch?v=8kO867TRAwQ M70 Vietnam Sniper: https://www.youtube.com/watch?v=XYX4Ce6vzHw
