This is a scope mount designed for firing projectiles with a lot of drop over distance (specifically foam darts). It was designed around a 30mm diameter scope, but the open top design should accommodate almost any size scope (not tested).

Mounts to standard picatinny rail using M5 hardware, either socket heads or hex heads with a 3D printed knob if you prefer tool-less adjustment.

Hardware:

(2) M5 bolts - either 30-35mm socket head or 40mm hex head if using the knobs (optional)

(1) M5 bolt - either 20-25mm socket head or 30mm hex head if using the knobs (optional)

(3) M5 nuts

(2) 8" zip ties - I used these reusable ones from Amazon

Rubber sheet/craft foam - I used some plumbers gasket rubber like this one, but any grippy sheet material should work, preferably 1-2mm (or 1/16") thick

Assembly:

1 - Insert front support into main body. Secure with M5 nut and the shorter of the three bolts. Feed the hex head bolt through the printed knob if you're using one.

2 - Cut rubber sheet into strips and glue them onto the front and rear scope supports.

3 - Line up both side clamp pieces with the main body and secure with M5 nuts and bolts.

4 - Set scope on top and feed zip ties through the holes. Tighten zip ties and feed loose ends back through the holes for a cleaner look.

5 - Mount the scope to your blaster and set desired slope.
