Hello GT, I am inquiring about a sling for my Nighthawk 870. I would love a 3 point sling because I am a huge fan of Specter Gear 3 points. Here is the issue, my SG has a pistol grip and a collapsible AR buttstock; if it had a normal SG buttstock I would get the specter SOP sling but it doesn't. Which sling would you guys recommend for a SG with a AR collapsible buttstock. Thanks in advance.
