20-Gauge Pump-Actions that Accept TLS Accessories for Added Versatility

When introduced in 2012, the innovative, patented and patent-pending system of Mossberg FLEX modular 500/590 shotguns and interchangeable TLS (Tool-less Locking System) accessories provided unprecedented versatility and the ease of converting your 12-gauge 500/590 shotgun in seconds without the need for tools. Now Mossberg has expanded the line to include 20-gauge with the introduction of four new 500 FLEX 20 gauge pump-action shotguns; available in hunting and tactical base models.

At the core of the 500 FLEX System is the patented “TLS,” a series of three connectors that allow stocks, forends and recoil pads to be switched for a variety of hunting/shooting applications or to easily re-configure your Mossberg FLEX shotgun to fit individual lengths of pull. Stocks can be interchanged with the simple lift and turn of the TLS latch on the receiver; remove the stock and slide the replacement stock onto the connector. Once aligned, simply turn the TLS latch 90 degrees clockwise and close the latch, locking the stock firmly in place. Forends and recoil pads are designed with TLS release buttons; when pushed, allow for the replacement of those components. Choose from 16 FLEX TLS accessories and Mossberg’s versatile line of 500 20-gauge accessory barrels to convert your base gun into a multi-purpose shotgun.
