Mesa LW Picatinny Side Rail

thingiverse

Add extra accessories and capabilities to your SE Mesa with these lightweight side rail pieces. Meant to directly screw onto the side of the angle iron, you can put the rail anywhere, or double up two on each side for 12" of extra rail space. The rail is canted 20 degrees to allow for better clearance of the pump grip. The rail is also skeletonized to reduce weight without compromising on strength. Due to this, supports are recommended for the bridging. Holes are #8, spaced 3" apart. For the rail, drill and tap #8-32 thread 1/2" from the bottom of the rail, which is in line with the holes for the front piece and rail holder. I drilled a hole every half inch, which lets me move the rail anywhere along the side, but if you want it in a fixed location, you only need two holes.
