SKS Red Dot Low Mount

This is likely the lowest Red Dot mount you can make, for an SKS. Even still, with this Viper attached, I am considering padding my stock by about half an inch, to get a proper cheek weld. But it will work without it, easily enough.

This should be printed "upside-down" (picatinny rail down), with "all supports" - that will support the hole, and create a ladder-support for the picatinny rail. Infill should be as high as you are willing to go, and something stronger than PLA would be a good idea, if your printer can handle it. The dimensions are tight on purpose, a very light filing may be needed, since some SKSes may be slightly looser or tighter.

The hole is sized to be ideal for a #6 fine machine screw.

There are youtube videos on how to remove the rear sight, and leaf spring.
