Alen key or power drill BACK HANDLE AND TRIGGER Start with installing the spring and trigger and assemble two sides of a handle using 2 M3x20mm bolts only through the lower two holes. MAGAZINE BASE Use super glue to assemble two parts of the magazine base. TOP BASE Install a separator by sliding it from above to a dovetail groove, fix it in place by drilling in a mini screw from above or gluing it in place. Joint the base and back handle with 2xM3x20mm bolts, and trigger with one M4x45mm bolt MAGAZINE Insert the pusher slide into any of two parts of the magazine then glue them together. The picatinny rail can be glued on top Make sure to inset M3 bolts on the back of the magazine Join the parts together, install the 8mm spring behind the magazine against the base and srew in one M3 20mm bolt into the magazine through the slot on the base. This bolt will activate the repeating action so make sure it slides easily Make sure that the separator slides in easily into the square hole on the back of the magazine, this is the most important part to tune. FRONT Join wingR , wingBase and wingBottom using two M3x25mm bolts through holes marked with red arrows, and one M3x20mm bolt - blue arrow. Install the front around the magazine base and assemble the other wingL the same way as the right one. Install the repeater on the left wing like in the picture using one M3x20mm, and one M3x25mm bolts. When the” repeating slide back” motion is done it should be pushing against the bolt protruding from the magazine and pushing it back against the spring smoothly. FRONT HANDLE AND LOCK Assemble the two sides of the handle with 2xM3x20mm bolts, then dovetail the upper part of the handle and use one more 20mm bolt to join the parts. Use soldering iron to inset one M5 nut through the square slot (red arrow) so that hole on the front is flush with the thread. Instal the front lock using one M5x25mm bolt. Instal the handle using M4 bolt (red arrow), instal the 8mm strong spring (blue arrow) Install the hands by sliding them in from above, slide in the locks and then use one M4x30mm bolt to fix them into place. This can be done after installing the rubber and the string since it is easier to tie the rubber when not under tension. Hands can be temporarily removed when the slingshot is not in use to preserve the rubber.
