The Model 146B uses a smooth cycling bolt-action with a T-style bolt handle and an adjustable trigger. Feeding is via an under-barrel tubular magazine cataloged for 20 .22 LR (20+1 capacity), with higher capacities for .22 Long and .22 Short per factory references.
Sighting equipment is a standout: a ramped blade front pairs with a barrel-mounted leaf rear sight with elevator, while the receiver carries the Mossberg S-130 Micro-Click aperture sight offering micrometer windage and elevation adjustments. This dual-sight setup supports both fine target work and traditional field sighting.
The 26-inch tapered steel barrel and blued steel receiver are complemented by a walnut stock featuring a Monte Carlo comb, cheekpiece, and pistol grip. Sling swivel studs are installed, and length of pull measures 13.0 inches.
Cataloged as a takedown design and drilled for Mossberg side-mount optics, this 146B reflects the era’s versatile smallbore approach. Overall length is approximately 43 to 43.5 inches with an unloaded weight around 7 lb. As a pre-1968 production rifle, it is consistent with serial number-exempt Mossberg long guns of the period.
