WHEN JIMMY MULLER SET OUT TO DEVELOP HIS LINE OF H2O WATERFOWL/ HUNTING CHOKES, HE HAD ONE GOAL IN MIND: TO DEVELOP ONE STYLE CHOKE TUBE TO OUTPERFORM EVERY CHOKE TUBE ON THE MARKET REGARDLESS OF THE HUNTER'S CHOICE OF AMMO. AND, HE DID IT. ALL MÜLLER CHOKES COME WITH A 60-DAY MONEY BACK GUARANTEE TO PROVE IT.

M is "modified," best all-around choice for bird and small-game hunting. F is for "full," for upland bird and waterfowl hunting. There are also specialized chokes for skeet and turkey hunting (the latter is called "extra full").
