This Winchester manufactured early variation 22" long barrel in 22LR caliber is for the model 77 semi-auto rimfire rifle designed for the detachable magazine and lacks the hold open button on the right rear section of the barrel which is seen on the late variation barrels. This barrel is in very good condition retaining most of its original blue finish with a couple scattered spots of rust and some light wear. The bore is bright and rates excellent. (file photos)
