Our HK Mark 23 picatinny rail adapter helps you mount any of your standard 1913 rail accessories! The rail adapter is printed in carbon-fiber filled nylon and it’s secured using a stainless steel bolt that attaches to the trigger guard. The bottom of the rail sits 9.5mm lower than the bottom of the stock integrated rail.

This product is 3D printed using durable and impact resistant carbon fiber filled nylon. The parts are annealed post print for improved impact resistance. Note, we do not guarantee that a laser mounted to this rail will hold zero.

Made in the USA.

Note: Firearm and magazine not included. This product includes the Picatinny rail and one stainless steel bolt.

Install: First, slide the adapter onto the front of the gun as far back as it will go until it contacts the trigger guard. Next, attach the rail using the included bolt. Tighten to a maximum of 12in-lbs. There isn’t any need for thread locker if your accessories back up against the screw head. If you have more space between the screw head and your accessories, you can use medium strength thread locker to ensure the fastener will not loosen during normal use.
