The Weaver SPR Tactical Thumb-Nut Optics Mount (brand part number 48375) is a one-piece mount for a 30mm scope, built with a forward cantilever to position the optic for proper eye relief on an AR-style rifle. Weaver machines it from aircraft-grade aluminum and finishes it in a durable matte anodize, with a thumb nut for tool-free field adjustments. Unlike the ring-free 1-inch version, this 30mm mount ships complete with its own ultra-high rings already included. It’s designed to work directly on a Colt AR-15-pattern rail for a sleek, low-drama optics setup.
