At SHOT Show 2012, Mossberg rolled out its revolutionary Flex shotgun, which allowed shooters to swap out stocks, forends and recoil pads to create a completely customizable shotgun. Now, the system has been applied to the company's MVP series, creating the Mossberg MVP Flex. A bolt-action rifle accepting AR mags is unique in itself, but the Flex system takes it a step further, making the MVP Flex customizable through interchangeable stocks, as well as the rifle's adjustable Lightning Bolt Action trigger. The MVP Flex sports a compact barrel and is chambered in .223. The MVP Flex will be available during the second quarter of 2013 with a price point under $900.
