Bryant Ridge's Analysis:
The O.F. Mossberg & Sons, Inc. Model 151M is a semi-automatic .22 caliber rifle introduced in 1946 and produced until 1958, notable for its refined sporting appearance and target-oriented features. Distinguished by its two-piece Mannlicher-style stock and factory target sights, the 151M was mechanically similar to the Model 151K and fed from a tubular magazine housed in the buttstock. Production changes were tracked through parenthetical subvariants rather than formal model names. The 151M(a) variant was produced from 1947 to 1948, followed by the 151M(b) from 1948 to 1954, and the final 151M(c) from 1954 to 1957, officially discontinuing that variant, although some rifles may have been completed or sold into 1958. Each subvariant reflected incremental factory updates while retaining the same basic action and configuration. Designed for small-game hunting, recreational shooting, and informal target use, the Model 151M and its variants have remained well-regarded by collectors for their distinctive Mannlicher stock, smooth operation, and classic post-war Mossberg design.
