Very good to excellent condition M1 Garand Winchester Op Rod. This op rod is correct for Early Winchester Garands built between Dec 1940 to Aug 1943. The lug measures .097, the original piston measures .5255 and the new dark gray parkerized finish is at 99%. The op rod catch hooks are excellent and ther e is no sign of ever dismounting in the bolt lug window. Check out the pictures, it's a pretty nice Op Rod! This has the modification so it's OK to shoot. Super nice Winchester op rod to help you restore your early WWII Winchester Garand.
