Western Auto Revelation Model 107 Chuckster .22 WMR Bolt-Action Rifle – 24" Barrel, 1960s Store-Brand Mossberg 640K Variant
Produced between 1959 and 1968, this Western Auto Revelation Model 107 Chuckster is the private-label counterpart to the Mossberg 640K. Chambered in the then-new .22 Winchester Magnum Rimfire, it was among the first commercial rifles to offer this cartridge. A polished blue carbon-steel barrel and receiver, Monte Carlo walnut stock, and detachable 7-round magazine give the rifle a classic mid-century American rimfire profile that collectors recognize instantly.

This Revelation 107 Chuckster carries the same dual-lug front-locking bolt found on the Mossberg 640K, providing solid lock-up for the higher pressures of .22 WMR. The 24-inch carbon-steel barrel is drilled and tapped for #12-48 scope bases, offering easy optics installation without gunsmithing.
The walnut Monte Carlo stock features a comfortable pistol grip and factory-installed sling swivel studs, balancing classic appearance with practical field use. A two-position lever safety sits conveniently behind the bolt handle for quick, intuitive operation.
Open sights consist of a serrated post front and an elevator-adjustable rear leaf, giving shooters a straightforward, reliable sight picture. The detachable magazine pattern pioneered here was later adopted by several Savage and Stevens rimfire magnum rifles, underscoring the design’s influence.
As a store-brand model exempt from serial-number requirements, this rifle highlights a unique marketing era when retailers offered exclusive versions of name-brand firearms. Its clean bore, intact rifling, and period-correct components make it a solid example for collectors of 1960s American rimfires.
