Launcher Red Dot Sight v2

This is version 2 of a red dot sight to be used for any launcher with slow moving projectiles that require a high angle of aim like nerf, 37mm, or 26.5mm.  It has preset notches at 5 degree increments from 0 to 35 degrees but aligning the top of the rear iron with the bottom of the triangle on the front iron gives it an additional 5 degrees.  It fits a Shield RMSC mounting plate because I found a cheap red dot for $60 on amazon with that footprint (price went up last I checked though).

Version two is much more compact than version one and the comparison is in one of the pictures.  My original intention was to cnc the risers out of aluminum but this is quite strong and I don't feel it is necessary now.  If the sight is put at 25 degrees or higher the indicator button serves as a cross bar for strength and the risers barely flex even when I squeeze them with pretty good force so it is safe to throw into a bag.

Sanding pieces with fine grit sandpaper and using the same lubrication you use on your printer rails makes it much smoother.  Sanding is definitely needed on the pegs for the red dot mount.  Unfortunately, this part needs to be printed vertically, otherwise no sanding would be necessary but minimal sanding on the sides of the pegs makes it fit quite easily.  I have plans to add different pistol optic footprints but haven't gotten that far yet.

I used m5 socket heads for the pic rail mount, and an m4-35mm socket head for the front hinge.  For the red dot mount, thin (1.8mm thin) square nuts are needed and m3-8mm button heads are optimal for the red dot but socket heads are pictured because that's all I had on hand.  The spring was a 6mm OD spring that I cut to length depending on how stiff it feels.
