The RAM Sling Loop is a bolt on sling loop with a slot for 1.25" slings.  It attaches to a rear ACE style receiver block by being installed between the stock and the receiver.  Longer 10-32 bolts are supplied with this product.  It can be installed so the loop is on either the left or right side of the receiver (reversible).

This loop is stamped from 0.160" steel sheet and then deburred.  It is finished with a dark grey manganese phosphate coating.

The pictured sling is a Vickers Blue Force adjustable sling.
