Premium-inspired rail leveling performance at a more accessible price point
The MK Machining Polymer Slim Low Profile Rail-Mounted level is our entry-level, budget-friendly option for precision shooters, hunters, and rifle builders who want dependable anti-cant performance in a compact rail-mounted package.
Inspired by the proven low-profile design of our XLP line, the SLP provides a clear, easy-to-read leveling reference in a durable Nylon 11 polymer construction made with advanced MJF technology. Its slim 0.450-inch housing takes up minimal Picatinny rail space, making it easy to add a level without crowding the rest of your setup.
The SLP Rail-Mounted Level requires just 0.260 inches of clearance between the optic and rail for installation. Its single-screw mounting design keeps setup simple, while pressed-in stainless steel rods add strength and durability to the polymer housing.
A white indexing line makes the bubble easier to center, and the vial is windowed on all sides to maximize available light and improve visibility from behind the rifle. The vial is also user-replaceable for straightforward long-term service.
Made in the USA and available in black or gray.
Why do I need a SLP Polymer Rail Level?
Just a few degrees of Cant will cause considerable shot dispersion at longer ranges! If the scope is Canted by only 2½ degrees, the bullet will impact .05 mils for every 100 meters in the direction of the Cant. This means with only a 2½ degree Cant and shot of 1000 meters would be an impact of .5 mils. A small change can make a big difference and the MKM Slim-Low-Profile polymer rail Level is a great solution.
But don’t just take our word for it. Here is a quote from Bryan Litz regarding Rifle Cant. Bryan Litz is the owner of Applied Ballistics and multiple time national and international competitive shooting champion.
As a general rule of thumb (for common cartridges) “a 1° Cant will produce five (5) inches of lateral displacement at 1000 yards. Thus, if you Cant your rifle just 8°, the POI would move 40″ from the center of the target, putting the shot off the edge of a 72″-wide target.” -Bryan Litz
