What’s Included
- Marlin Model 99M1 .22 LR semi-automatic rifle
Styled to echo the U.S. M1 Carbine, the Model 99M1 carries the same compact barrel length and distinctive handguard profile, yet chambers economical .22 LR. The hardwood stock features a Monte Carlo comb that aligns the shooter’s eye naturally with the iron sights or an optional rimfire scope.
Marlin’s 16-groove Micro-Groove barrel technology delivers a smooth bore surface and precise rifling for consistent accuracy with standard .22 LR loads. The 18-inch steel barrel is dressed in traditional bluing that matches the black alloy receiver.
A flush 9-shot tube magazine keeps the fore-end clean and balanced. The receiver includes factory-cut 3⁄8-inch dovetail grooves, allowing quick installation of tip-off rimfire optics without gunsmithing. Ramped front sights with protective ears pair with an elevation-adjustable rear leaf for precise iron-sight work.
Controls are straightforward: a cross-bolt safety, a smooth gold-tone trigger, and Marlin’s proven blowback action known for dependable cycling with a wide range of .22 LR ammunition. Overall, this Model 99M1 offers a collectible blend of period styling, practical features, and renowned Marlin build quality.
