I'm gonna use the make ur own tac sling for my 870 and I have the Wilson Combat +2 with the side sling loop for the front, but I need a butstock adapter for the rear.  Can someone point me in the right direction?  thanks,

Doc

GG&G makes a buttstock sling loop that fits between the buttstock and the rear of the receiver.

Also, the tactical shotgun sling from Eagle Industries comes with a velcro wrapped sling loop that attaches near the recoil pad of the buttstock and uses the existing rear sling stud to maintain position.  They may sell you this piece separately.

Check out their websites for actual pictures, so my crappy explanation makes more sense.
