The Mossberg MVP FLEX Bolt-Action Tactical Rifles bring the FLEX TLS™ (Tool-less Locking System) to its family of MVP Series Bolt Actions. Chambered in 5.56mm NATO (223 Rem.) and 7.62mm NATO (.308 Win.). The FLEX TLS allows removal and remounting the rifle's stock without tools in seconds. These rifles deliver a bolt-action engineering breakthrough with the MVP's patent-pending Drop-Push bolt, designed to accept and reliably feed from AR-style magazines. Adding to the rifle's precision performance is the patented Mossberg (Lightning Bolt Action) LBA™ Adjustable Trigger System, which is user-adjustable from 2 to 7 lbs. Even at the lightest adjustment setting, the unique lightning bolt trigger blade blocks the sear from releasing the striker unless the blade is fully depressed. Other standard features on the MVP FLEX Rifles include fluted, button-rifled barrels with a FLEX six-position tactical stock, durable matte-blued finish on exposed metalwork, receiver-mounted Picatinny rails, distinctive spiral-fluted bolts, front and rear sling swivel studs and 10-round capacity magazines. Rifle stocks and recoil pads are adjustable to fit individual shooters. Standard FLEX stocks also allow for interchangeability of recoil pads with a simple TLS connection and choice of small (3/4"), medium (1-3/4") or large (1-1/2")FLEX accessory recoil pads.
