This Winchester manufactured sixth variation bolt assembly with a checkered radius on the firing pin head, second variation bolt body and third variation firing pin is for the model 02A bolt action rimfire rifle in 22 S. L & LR caliber. This bolt assembly is in very good condition exhibiting a grayish brown patina with light wear. This bolt assembly will NOT work in the earlier model 1902 or 02 rifles chambered in 22 S, L or XL caliber.  (file photo)

Note: One distinct difference between this and earlier bolt assemblies is that this version has the firing pin return spring.
