Mossberg has introduced FLEX Conversion Kits for the Mossberg 500 and Maverick 88 pump-action shotguns in 12- and 20-gauge options. Three conversion kits are available for each gauge with all required hardware included.

With this new conversion kit, Mossberg hopes to deliver the flexibility and versatility of the FLEX system to the owners of existing 500/88 pump-actions.

Available kits:

Stock and Fore-end Adapter Kits
Includes the FLEX TLS stock and fore-end adapters only, but provides the option to switch to FLEX accessory stocks, recoil pads and fore-ends on your Mossberg 500 and Maverick 88 shotguns.

Stock Adapter with FLEX Pistol Grip Kit
Includes the FLEX TLS stock adapter and Mossberg's FLEX Pistol Grip with convenient sling swivel stud and black matte finish. Easily convert your 500/88 to a Mossberg Cruiser platform for home-defense applications.

Stock Adapter Kit
Includes the FLEX TLS stock adapter only. This kit will allow your 500/88 to accept FLEX stocks and pistol grip for LOP (length-of-pull) customization or ease of converting your hunting shotgun to tactical platform.

Currently, the company offers 16 FLEX accessory components and an extensive line of accessory barrels. FLEX System accessories include three recoil pads (3/4", 1 ¼" and 1 ½" thick); four synthetic fore-ends (three standard and one tactical tri-rail); and nine stock options. Choose from standard full-length stocks with 12½-, 13½- and 14 ¼" LOPs; pistol grip; six-position adjustable tactical stock; and four-position adjustable, dual-comb hunting stock. Fore-ends and stocks feature black matte, Mossy Oak Break-Up Infinity or Realtree MAX-4 finishes.
