Not really tactical, but I call it practical tactical. My do it all 870 Super Magnum, this is HD set up, this barrel is the 21" turkey barrel which is perfect for HD and 3 gun I feel, but have a slug barrel and 28" barrel for hunting and trap. Just got done refinishing the ugly blonde stock in a custom stain and poly.
Just finished up this build. Always wanted a Marine shotgun so found a steal on a new 500 Mariner. Added a ATI Talon stock which is awesome and really helps with recoil, a ATI shell holder rather than the cheek riser, Meprolight front night sight, and a laserlyte tube rail for a light.
And the two together
