Anti-rotation tabs and set-screws ensure that your rail will not rotate, even under the most extreme conditions of use. M1913 picatinny rail on top and M-LOK™ slots on every quadrant ensures maximum customization for all your accessories. The Geissele SMR MK16 is precision machined using 6061-T6 Aluminum due to its strong, rigid and light properties, and is finished in durable Type-3 Hardcoat anodized.

Please Note: Geissele DDC, or Desert Dirt Color, refers to the variety of shades of desert terrain. Differing shades of DDC are desired on a military small arm to breakup the outline of the weapon. These colors can vary from color seen in the picture of the product, and can also vary from each other when comparing one product to another product. Due to the chemical process that takes place during Type 3 Hardcoat, the finish on the product can vary from one to the next, even if it is the same batch.
