Hi, I'd sure appreciate your sending those 7188 photos. As for my 11-87, it has an 18-1/2" barrel. Bead front sight. From the sounds of it, the 7188 is a dead ringer for the 11-87P except for an integral bayonet lug/forward mag tube bracket???
Does this mean they have an indentical operating system except for the full auto feature? I'd be glad to hear what you know about the 7188.
Concerning the military type sling, yes, I'm planning on mounting it on the 11-87P. I've found a sling maker who's work is superb. Check'em out at www.turnersling.com.
This guy knows how to build a sling!!
