This Mossberg 940 Pro Tactical (brand part no. 85152) is a 12 gauge semi-auto shotgun built for defensive use, combining an 18.5-inch cylinder-bore barrel with a 7+1 capacity for extended rounds on tap. Mossberg built the 940 platform around a durable gas system rated for up to 1,500 rounds between cleanings, with nickel boron-coated internals on the gas piston, magazine tube, hammer, and sear for corrosion resistance. An optic-ready receiver and M-LOK-compatible barrel clamp let owners set the gun up exactly the way they want it, from red dot to weapon light.
