The Trijicon RMR Type 2 is a micro red dot optic designed to improve target aquisition speed and accuracy of nearly any weapon platform, from compact and full-sized handguns to shotguns, carbines, and long guns. The lightweight Ruggedized Miniature Reflex sight is also ideal as a backup optic and featuers an open sight picture, allowing the shooter to simply place the red dot on the target, rather than focusing on aligning iron sights.

With a rugged forged aluminum housing, the RMR Type 2 is designed to stand up to the harsh recoil of a semi-automatic pistol slide, and is waterproof up to 20 meters. The durable forged aluminum housing features new tactile click-adjustments for easier and more secure zeroing. The electronics have been ruggedized and easily controlled with ambidextrous power controls.

Custom Kydex Holsters — precision-molded for any firearm, built to last.
At River Otter Tactical we craft custom Kydex holsters that marry surgical fit with real-world ruggedness. Every holster is thermoformed to your exact firearm and configured to your carry style — IWB, OWB, appendix, shoulder, ankle, mag carriers, and more. We engineer retention, draw angle, and ride height to your personal preference so the gun sits where you want it, how you want it.
What you get:
Exact-fit Kydex molding for any make/model — zero wiggle, consistent presentation.
Adjustable retention and audible positive lock for secure carry and smooth reholstering.
Multiple mounting options: belt clips, QLS, loops, wedge plates, or MOLLE-ready attachments.
Configurable cant, drop, and ride height to optimize concealment or speed.
Fully finished edges, sweat guard, and trigger coverage to maximize safety and comfort.
Durable finish choices: matte, textured, or custom patterns and colors — show subtle stealth or bold style.
Optional upgrade: multi-layer retention systems, upgraded hardware, or concealment wing.
Why it matters: Kydex is lightweight, weatherproof, and rigid — it won’t sag or deform with use. A custom mold means consistent draw stroke every time, faster presentation, and repeatable reholstering. As veteran makers, we combine battlefield-tested practicality with meticulous shop-level precision.
Built for your mission: Submit your firearm model and carry preferences, choose the mounting and finish, and we’ll deliver a holster tuned to your daily routine. From concealment to duty rigs, we innovate the fit so you focus on what matters.
River Otter Tactical — veteran-crafted Kydex that locks in, draws clean, and keeps you ready.

We may need to borrow your knife briefly to create an exact custom fit. Proper protection and tracking are used while your knife is in our care, and return shipping is included unless other arrangements are requested. Contact us to discuss options, lead time, and any special requests.
