Marlin Model 99 M1 .22 LR Semi-Automatic Rifle, 18-Inch Micro-Groove Barrel, 9+1 Capacity
Marlin’s Model 99 M1 blends the proven Model 60 action with the look and handling of the U.S. M1 Carbine. Produced from 1964 to 1978 in limited numbers, this carbine-length .22 LR features an 18-inch Micro-Groove barrel, a 9-round tubular magazine, and a distinctive gold-anodized trigger. Collectors value the Model 99 M1 for its short production run, milled steel receiver, and period-correct hardwood furniture with separate handguard.

What’s Included
- Marlin Model 99 M1 .22 LR semi-automatic rifle with 18-inch barrel and integral 9-round tubular magazine
The Model 99 M1 uses a blowback semi-automatic action that feeds from an under-barrel tubular magazine, giving the shooter 9+1 rounds of .22 LR without protruding magazines.
Its 18-inch Micro-Groove barrel provides 16 shallow lands and grooves, a design Marlin introduced for increased bore contact and easier cleaning. The bore on this example retains defined rifling, supporting good accuracy with standard or high-velocity loads.
A straight-grip hardwood stock with white-line spacer and matching handguard delivers classic carbine lines. Factory sling swivel studs make it simple to add a carry strap, and the 13.75-inch length of pull suits most shooters.
The receiver is both drilled and grooved for tip-off rimfire scope mounts. Adjustable open sights—a drift-dovetail front blade and receiver-mounted rear—are installed for immediate use.
Period touches such as the gold-anodized trigger, alloy trigger guard, and cross-bolt safety give the rifle distinctive 1960s styling while maintaining practical function.
