Many years ago, the clas­sic Brown­ing B25 Su­per­posed de­sign was mod­i­fied to fa­cil­i­tate mass man­u­fac­ture. Ja­pane­se­made Brown­ings and Mirokus are made to a slightly sim­pli­fied de­sign that dis­penses with a de­tach­able fore-end and there­fore some ac­tion ma­chin­ing (B25s have a hinged ex­ten­sion to the fore-end iron that en­gages in a key­way in the gun’s ac­tion belly). The 725 is a more rad­i­cal mod­i­fi­ca­tion, or, rather,

evo­lu­tion, of the ba­sic and much copied John Moses de­sign. It re­tains a full-width hinge pin and bolt but does this in a sig­nif­i­cantly low­ered ac­tion. The ham­mers are pow­ered by coil springs hinged to the bot­tom strap. The re-en­gi­neered sin­gle-trig­ger mech­a­nism is me­chan­i­cal – prefer­able in a game gun be­cause of its re­li­a­bil­ity, no mat­ter the pay­load. The trig­ger pulls are im­proved. The 725 also in­tro­duced a new, im­pres­sive

chok­ing sys­tem, the ‘DS’ (Dou­ble Seal). The chokes are, un­usu­ally, threaded to the front; there is a cop­per ring ‘com­pres­sion seal’ to the rear. Both frontal thread­ing and the rear seal pre­vent gas leak­age. Ejec­tors are the fa­mil­iar ham­mer pat­tern

pow­ered by coil springs.
