The stock’s finish is largely intact, and the stock fits tightly to the barreled action, with no play. The stock appears to have been refinished at some point in its life, as there is evidence of sanding in the checkering. There is one small chip on the bottom of the left side of the wrist, and one small chip in the checkering on the right side of the wrist. There are no visible cracks, and no structurally compromising issues. Overall, the stock rates in Good condition.

Our Assessment: The Winchester Model 100 chambered in .284 Winchester stands as one of the most interesting and least common factory offerings in Winchester’s post-war sporting rifle lineup. Introduced in the early 1960s, the Model 100 was Winchester’s flagship semi-automatic sporting rifle, and the .284 Winchester chambering brought genuine innovation to the platform. Designed to deliver .270- and .280-class ballistics in a short action, the .284 Winchester is now highly regarded by knowledgeable collectors, especially when encountered in factory semi-automatic form.
This 1965-manufactured example retains approximately 95 percent of its original metal finish, with light, honest wear visible throughout. Minor scratches, small dings, and light thinning at the top of the receiver near the scope base are present, along with early oxidation beginning on the barrel and bottom metal, all consistent with careful field use rather than abuse. The bore is a standout, remaining bright with sharp rifling and no visible erosion, earning a 10/10 bore rating. Factory iron sights remain intact, and the rifle is currently fitted with a one-piece Weaver base and rings, allowing straightforward optic mounting while preserving the rifle’s classic profile.
The press-checkered walnut stock shows evidence of an older refinish, with some sanding visible in the checkering, along with small chips at the wrist that do not affect structural integrity. Fit to the action remains tight and solid. The included 4-round magazine, originally for the Model 88 but fully functional in this rifle, feeds properly, though it does not lock the bolt open when empty, a known compatibility quirk worth noting. With its correct configuration, desirable chambering, and strong mechanical and bore condition, this Winchester Model 100 in .284 Winchester represents a scarce and historically significant variant that will appeal to collectors of classic Winchester semi-automatics as well as enthusiasts of uncommon factory chamberings.
