What’s Included
- Mossberg Model 146B .22 S/L/LR bolt-action rifle
The Model 146B is configured with an under-barrel tubular magazine rated at 15+1 rounds of .22 S/L/LR and a right-hand bolt with a round knob. The 26-inch steel barrel and blued steel receiver deliver the classic construction and finish associated with Mossberg’s post-war rimfire lineup built in New Haven, Connecticut.
Sighting equipment includes a hooded ramp front sight, a folding rear leaf sight, and a receiver-mounted aperture/peep sight consistent with the period S-130 pattern. This setup provides fine elevation and windage control while retaining a traditional iron-sight profile.
The hardwood stock incorporates a pistol-grip profile, a Monte Carlo comb with a cheekpiece, and quick-detach sling swivel bases. A coin-slot takedown fastener allows the rifle to be separated for transport or maintenance without specialized tools. The stock is smooth with no checkering, reflecting the factory style for this model.
Safety indicator dots (green/red) provide a clear visual reference for the safety position. The rifle’s dimensions are practical and well-balanced for rimfire use, with an approximate factory weight of about 7 lb, an overall length around 43.3 in, and a 13.0 in length of pull.
As a post-WWII American rimfire, the 146B combines period features and durable materials. Its design—blued steel, hardwood furniture, tube magazine, and receiver aperture sight—captures the practical engineering that defined Mossberg’s mid-century .22 lineup.
