if your right handed, the peq-16 goes on the right rail, I usually put my laser even with the forward most rail. we also use vicker tactical (blueforce gear) 2 point slings.yes! what do you mount on your side rail when you say you mount you 16's? I think I just figured it out... you're talking about the sling right? Is it specter gear 3 point? or 2 point? I just cancelled my order for the specter 3 point, as I hear 2 point is much better on a long rifle.
I don't remember what adapter we use, but its just some low bid rail adapter.
we use the 15 also, it's just not as common. I just took a quick look at the photo and it looked like a 16 to me. same thing applies though. dominant side rail.ah I'm using PEQ-15's.
