Description
A 34mm accessory ring cap that replaces the front or rear cap on Trijicon Q-LOC and Slimline style mounts, for professional users adding optics.
The Trijicon 34mm Accessory Ring Cap replaces the front or rear cap supplied with Q-LOC style mounts and is made from Mil-Spec drop-test rated 6061-T6 aluminium. Three mounting locations, at the 12 o'clock and 45° positions, allow a red dot sight or a Picatinny rail mounting plate to be attached to the cap.
It integrates with Trijicon Q-LOC and Slimline style variable power mounts, letting a lightweight cap add further optics or components to build a complete optics system on one mount. It has a matte black anodised finish.
