The Strike Industries Tribus Enhanced Castle Nut and End Plate (brand part number ARTRIBUSRED) is the next iteration of Strike’s earlier AR-ECN&EEP, adding two more QD mounting points to the left and right of the extended end plate for a total of three. Strike Industries pushes those QD mounts back away from the webbing of the shooting hand, so a sling attached to the end plate doesn’t pinch or startle a shooter during hard weapon manipulations in tight spaces or under stress the way a standard flat end plate can. The other major upgrade is an anti-rotation castle nut: once installed, a set screw locks it in place to keep the castle nut from backing out during use, eliminating a common source of stock wobble. It’s finished in red as part of Strike’s broader anodized color line.
