I bought the SOC-C contracter's pack a long time ago from G&R, had to special order it then.
It's nice, it comes with all sorts of parts and pieces. The only things I didn't like were placements of certain elements of the main sling. There are some parts I would have liked to move or 'reverse' but the entire sling is sewn together so you can't remove any parts, translated to "lose them."
My sling is in a 3-point config right now. I am using one of the neat little buckle attachments that consists of a small strip of velcro that has hooks on one side and loops on the other. It wraps through a non-swivel mount on my FF forend just forward of an 11-rib KAC panel and then through the plastic female end. It is held together by a 1/4" strip of velcro that is also included:
The rear is connected directly to the a$$ end of my buttstock using a female buckle that is attached to a 6" strip of webbing with two rings on it. It is meant to be looped through a sling plate or attachment like I'm using on the front, but I chose to just rivet it into the rear of my buttstock and then cut a little rubber from the buttpad so it's somewhat neat looking:
Here are a few other pictures of it including the elasic keepers - both included and captivated. This first one is doing absolutely nothing but keeping the looped webbing from opening up:
This one is keeping a separate male buckle from sliding around on it's own. I found no use for this buckle and trimmed the forks off of it. I had used the remaining part as a simple D-ring at one point but went with my rear stock "mod" instead. You can see it's causing the snug to bulge and keeps the sling from sliding too far through the buckle:
here is the front end of the sling where it all comes together and some of the adjustments are made. You can see how far I have adjusted the ring and how much is left if you wanted the "Y" of the sling to be further back:
There is still a about 10 pieces left in the pack.
I've got 3 H&K snaphooks that came with it and there is another of the little velcro strip setups that was supposed to be used with the snaphooks. There were two female buckles on the ends of ribbons, one long and one short, the longer being the one in this picture:
There was also a nice rugged setup for the front of a rifle with standard handguards like A2 or M4 handguards that has a very rugged strip of velcro that secures it to the front sling swivel:
and, last butt (
) not least, the A2 rear stock setup:
