I think some super early field testing batches of M1C could actually reach the front in very small numbers but haven't seen a lot of action. It was adopted in 1944, but issues with accuracy prevent if from replacing Springfields in the sniper rifle role. But I've read memoirs of a German sniper who encounter a G.I. with a "self loading rifle with a scope mounted on the side of the receiver". It was the day he surrendered tho
If we will ever get a super late war map with USA vs Germany, I wouldn't mind seeing a single scoped Garand hidden somewhere as an easter egg kit, we have historically inaccurate STG44 ZF after all. I would rather see a field modification of G41 with ZF41 scoped first, now that weapon is cool, and we have maps it could be used on
