Marlin Model 99 .22 LR Semi-Auto Rifle, 22" Micro-Groove Barrel, 17-Round Tube, 1959–1961 Production
This Marlin Model 99 is a first-generation, rimfire semi-automatic rifle produced between 1959 and 1961. Collectors value it for its early Micro-Groove rifled barrel, generous 17-round tubular magazine, and classic walnut-finished hardwood stock. The gun’s period-correct features, combined with its limited production window, make it a notable find for anyone seeking an authentic mid-century Marlin .22 LR.
Condition
Overall Condition: Fair condition, showing extensive signs of prior use and handling.
Bore Condition: Fair - Generally clean, some residue or smudges, slight corrosion.
Bore Rifling: Good Rifling - Intact, well-defined lands and grooves.
The metal surfaces display scratches, blemishes, and areas of light rust and pitting. The magazine tube has separated from the barrel; it still functions but has a small amount of play. Despite external wear, the bore remains shiny, and the action cycles correctly.
What’s Included
- Marlin Model 99 .22 LR semi-automatic rifle
Marlin’s Micro-Groove rifling delivers a high count of shallow lands and grooves, giving this 22" carbon-steel barrel a reputation for consistent accuracy with standard .22 LR ammunition.
The rifle feeds from a 17-round under-barrel tubular magazine, offering ample capacity for casual plinking, small-game hunting, or range practice without frequent reloads.
Anodized aluminum keeps the receiver lightweight, while the steel barrel and blued finish provide durability and the classic Marlin appearance of the era.
The walnut-finished hardwood stock features a Monte Carlo comb and pistol grip, giving shooters a comfortable cheek weld and a traditional look. Length of pull measures 13.5".
Factory iron sights include a ramp front sight and a semi-buckhorn adjustable rear sight. The receiver is drilled, tapped, and fitted with rails, so adding a scope is straightforward for those who prefer optics.
