I recently bought a 1.25 inch wide Montana Sling and tried it out on my M77MKII 350 Rem Mag. I have always been a big fan of the 1907 style military slings and the Swede M41B sniper style slings.

I had avoided the Montana sling because I could not see how the heck they weird braided knot they put in the leather could work as well as a buckle set up.
Well I was wrong to wait.
This sling really works. It takes up less room than the 1907s because there are less pieces. It does not have any metal hooks to reflect light, make noise or scratch anything. And some how or another the darn knot thing actually works and stays right where you set the sling length.
