My bad guys. I didnt realize I was redirected to another site. Harris tatical. Ill post the link amd see what you guys think.... im more jist wondering how it fit a 18.5" barrel. Thier site says min of 18" I was just curious.
Here's what I see.
1. The rail hight with optics or irons is gonna require some cheek piece or riser on the combof the stock. I've used that exact red dot on a receiver rail and its less than comfortable at best.
2. The description does say it won't work with 5 shot models which will rule out an 18 1/2" gun. It would take a 20" barrel for it to work and I'm honestly not sure how it would work on a 20" 590 if the bayonet lug gets in the way. I thought all 20" 590s had the bayonet lug unless its only the A1s with the heavy barrel. It may work on an 18 1/2" 590 with a magazine extension.
