The Mossberg 940 Pro Field is an advanced, gas-operated autoloading shotgun purpose-built to withstand the grueling demands of waterfowl, upland game, and competitive clay shooting. At its core lies a revolutionary gas-venting system featuring clean-running internal parts heavily coated in corrosion-resistant nickel-boron, which allows the shotgun to reliably cycle up to 1,500 rounds between field cleanings. The slim synthetic stock and streamlined forend are dipped entirely in the highly protective Veil Ancient Bark Camo pattern and wear an aggressive texturing overlay to guarantee a slip-free grip in freezing rain or swamp conditions. Shooters can seamlessly customize their mounting stance via an included set of drop shims, cast plates, and length-of-pull spacers that adjust from 13 to 14.25 inches to match varying torso frames or thick winter layers. Complete with an oversized bolt handle, an enlarged beveled loading port with a quick-empty magazine release, and a bright red fiber-optic front bead riding its 28" vent rib barrel, this autoloader ensures lightning-fast target acquisition and seamless reloads when every fraction of a second counts.
