Meet the TRIBUS Enhanced Anti-Rotation Castle Nut & Extended End Plate, the evolution of our previous AR-ECN&EEP model. Notable enhancements include dual supplementary QD mounting points on the left and right sides of the extended end plate, totaling 3 QD mounting points. This innovative design relocates the QD mounts on the extended end plate, reducing discomfort and the potential for pinched hands when using a sling attached to a standard, flat QD end plate. This ensures smooth weapon manipulation, even in confined spaces and high-pressure scenarios. A significant improvement is the integrated anti-rotation castle nut, which, after installation, secures the castle nut to prevent unintended loosening during weapon deployment. The TRIBUS is also available in our range of anodized color options.
