Hey guys, im going to be buying a BAT quad rail in the near future and figuring out what sights to run now that i will have all kinds of real estate. Ive been looking at a Bushnell TRS-25 and Magpul flip up sights, both front and rear. My Mossberg 500 has the 18.5 inch barrel so the sights arent that great on it, so the possibilities are endless with a quad rail. Im looking to see how anyone has run a similar setup to what i have in mind. Will i need to get a riser for the red dot (either Bushnell or Primary Arms)? just to get everything to co-witness? Any help (and pictures!) would be greatly appreciated!
