This Mossberg Flex review examines what makes this 12-gauge shotgun so versatile: TLS (tool-less locking system). The Mossberg Flex is a great survival gun.
The new Mossberg Flex continues the long tradition of the popular Model 500 shotguns, but with a twist. The stock, forend, and recoil pad of the Mossberg Flex can be changed in than a couple minutes with no tools.
This is true for any of the 12-gauge models in the Mossberg Flex series: the Flex 500 All-Purpose, Flex 590 Tactical, Flex 500 Tactical and Flex 500 Hunting.
The TLS is the Key

The TLS (tool-less locking system) is what makes this system work. It was tested by the military, and they heaped abuse on the shotgun and the TLS system.
It works like this: A zinc coupling and socket locks the stock to the action. The bolt is
pulled up, turned and the stock comes off.
The forestock comes off and attached by way of a spring latch. Changing the recoil pads is as easy as pushing a button.
Transform the Shotgun
The Mossberg Flex can be transformed from an all-around utility shotgun, to a turkey gun, a waterfowling gun, a slug shooter for deer or as a tactical shotgun for home defense.
Barrels offered range from a 28-inch ventilated rib to a short and stout breaching barrel for tactical uses.
There are three sizes of recoil pads and a wide variety of stocks and forends are available in black, Realtree and Mossy Oak camouflage.
The Mossberg Flex versions available range in price from approximately $600 to $750 depending on numerous add-ons.
