Heat Shield to fit Mossberg 500/ 590/ 835 12 guage smooth barrels +  Defender Tactical Mini Shell Adaptor

This new partnership with Defender Tactical allows the use of the now prevalent MINI ShotShells from Aguilla (And Others) to ensure optimal Cycling.  (SEE PHOTO FOR REFERENCE).

Mini Shells are AWESOME to save the shoulder and excellent for female shooters defending the homestead.

Also includes a HIGH VIZ Red Milled-Aluminum Follower to complete the package!

Installs in about 2 minutes.  There is a great video tutorial on the Defender Tactical Website (See QR Code on the back of packaging) 



Its a BEAUTIFUL DAY in the pump-shotgun world!  We now have modified heat shields to fit the Mossberg 590A1.  These are hand-fit on our in-house 590A1 to fit the dimensions of the Mossberg A1 Heavy-barrel.  



Our design modifies the brackets and inner-rings for geometry reasons.  Shield will hide about 90% of your standard brass bead, but blade sights are perfectly visible.   All hardware and brackets are included (Will include 2 sets of zinc-black screws in 8mm and 12mm length). There will be a small 1-2mm gap between the brackets (This is normal, and dont over-tighten).  See the included photo of the ONE model (Short 7rd mag-tube) where this shield will NOT work.  This a 'rough-cut' modification, so its not going to be 100% free of burrs or sanding marks, but we will keep the price reasonable on the labor costs.  As usual, all our shields are warrantied FOR LIFE! You break it, lose it, or throw it off a CLIFF......we will replace it for LIFE.

Remember, this is a prototype, and if you dont like it, shoot us a ring.  We are NICE GUYS!

About the Shell adaptor:

This kit essentially provides a conversion to 590S functionality, but in a more robust design. It contains our patent-pending Universal Cartridge Adapter and low-drag no-snag Magazine Follower which allows smooth cycling of 1-3/4" Minishells up to 3" Magnum cartridges in the same magazine. The adapter is constructed from vulcanized thermoplastic rubber, and the follower is machined from solid 6061-T6 billet aluminum. This kit is compatible with any Mossberg 12-Gauge pump-action firearm with a 3" Chamber and machined grooves in the receiver. Please refer to the picture below or the installation video below to confirm your firearm's compatibility.  


Please note there may be a short break-in period for some adapters after installation. Cycle a few magazines of full-size shells if you initially experience issues with 1-3/4" shells, please reach out to us if problem persists.  


*The Cartridge Adapter and Magazine Follower are optimized to function as a pair, but the factory follower may function as well for those that do not wish to remove it.
