Sidelok Absolute Co-Witness Mount Qd For Trijicon Rmr Black
Kinetic Development Group
The Sidelok Low Mount QD for Trijicon RMR is a quick-detach optics mount from Kinetic Development Group that strips away complexity in favor of speed and reliability. This low-profile RMR mount uses a simple push-button design to lock your sight onto a Picatinny rail without tools, levers, or awkward knobs—you can strip your optic and remount it in seconds. For shooters who run multiple firearms, swap optics between platforms, or need to pack light on a hunt or range trip, the Sidelok delivers real-world utility without sacrificing zero shift.
The engineering here matters: Kinetic built the Sidelok to maintain zero and return consistently to the same point of aim when you remount the optic in the original position. That's not a marketing claim—it's the difference between a convenient mount and one you'd actually trust on a duty gun or hunting rifle. A safety detent prevents accidental movement or separation during use, so you're not second-guessing your setup in the field.
Finished in black anodize, the low-profile design won't tower over your slide or receiver. It's lightweight at 2.4 ounces and compact enough to integrate into tight mounting spaces. Sidelok supports a broad range of red dots—Trijicon RMR and SRO, Holosun 407/507/508/509 series, Swampfox, Vector Optics, and others—making it a versatile choice if you're building a modular optics ecosystem.
