Browning R1-1-15-16 QD Bushing

Browning R1-1-15/16 QD Bushing is a Browning Split-Taper QD bushing with a 1-15/16 inch bore (1.9375 in), intended for quick-detach mounting in Browning drive and spindle assemblies that use split-taper bushings. It features a flange outside diameter of 2.6875 inches and a through-bore length of 1.2500 inches, specifications that align with the R1-series split-taper design used across Browning catalogs. The QD designation identifies the quick-detach interface, allowing faster mounting and dismounting of compatible components in the system. Zoro’s Browning listing for the 1-15/16 bore notes a small-end barrel diameter around 2.5567 inches and a large-end barrel diameter around 2.625 inches, consistent with the bushing’s taper geometry; Radwell lists this model with a weight near 9 pounds. Cross-reference documentation confirms the model as R1-1-15/16 (R1 series) and maps to Browning’s 1-15/16 bore split-taper bushings across multiple suppliers.
