The M25, 1949-1954 only in 12 gauge had the one fubar WRA clowns tried out- also on the M12 Heavy Duck guns of that era- the so-called "Dog Leg" style op. rod-- see the Madis book for more details if you'd like. None of my 7 12 gauge M12's have that design snafu-earliest dates to 1921, latest to 1949-- after the Remington 870 replaced the fine M31, WRA guys were scrambling to cheapen their mfg. costs of the M12 (and M21) and still turn a profit- disaster-- RWTF
