Mossberg 514 Short Barrel Conversion Kit 14" Black 12 GA for Mossberg 500/590/590A1 with 6Rd Magazine Tube

The Mossberg 514 short barrel conversion kit gives you a compact, maneuverable 12-gauge shotgun built on the proven Mossberg 500/590/590A1 platform. This 14-inch heavy-wall barrel transforms your existing pump action into a purpose-built firearm for home defense, law enforcement training, or tactical applications where a shorter overall length matters. The kit ships with a 6-round magazine tube, so you get everything needed to complete the conversion on a compatible Mossberg receiver.

Mossberg's 500 and 590 series have earned their reputation through decades of hard use—military adoption, police departments, and hunters worldwide trust them because they work. This conversion kit carries that legacy forward: a heavy-wall barrel with cylinder bore choke for tight, predictable patterns, a traditional bead sight for quick target acquisition, and a Parkerized finish that resists corrosion and wear. The shorter barrel reduces weight and length without sacrificing reliability or the shotgun's legendary durability.

Whether you're building a compact home-defense shotgun, setting up a training platform, or reconfiguring an existing Mossberg for a new mission, this 14-inch barrel kit is a straightforward, cost-effective upgrade. It's the kind of practical, no-nonsense component that defines the Mossberg platform—proven design, honest performance, no marketing hype.
