Use this Sun Optics Loop Swivel Set to attach your sling or strap to your lever action rifle. Each loop is 1" (2.5 cm) wide and can be quickly detached from the mounting studs without tools if you want to remove your sling and swap it for another or you need to strip, clean, or service your firearm. This version comes with a front barrel band that fits barrel diameters from .610" to .670" and 3/4" rear wood screw. The band and screw are topped with a mounting stud for the swivel loop to attach to, and a set of spacers are included to ensure a perfect fit. The swivel loop, band and screw are made in the USA of strong and durable steel treated with a black satin finish.
