Madbull have sent over details of the Strike Industries ambush sling loop:
The Strike Industries Ambush low profile sling loop is the lowest profile sling loop designed for the MIL-STD-1913 rail. Made of solid steel, its unique locking bar design system allows for it to be light weight and durable. Because the Ambush sits flat in between the rails, it will not interfere with your sights and fit neatly under longer optics when mounted towards the middle of the rifle. The dual purpose loop and swivel sling attachments allows the user to choose which mount they would like to use.
Package include:
» 1 x Ambush Sling Loop
» 1 x Screw
» 1 x Universal QD Swivel Locking Bar
Features:
» Made of solid steel
» Dual purpose loop and swivel sling adapter
» Lowest profile sling mount
» No interference with optics*Note: QD sling swivel and sling not included
Depending on the manufacturer of QD sling swivels, there will be slight variations in fitment with our Ambush sling loops. Test fit and pull hard on your QD sling swivel before use
