Bộ kit phụ kiện BK1S "Spite" Tactical Machine Pistol

A simple build from the 3d print perspective BUT! you will need to solder an extender for your battery cable. Ive used an XT60 connector with around 100 to 140 mm of wire to reach the battery pack, (any junctions you add can be hidden under the small riser on the rail cover)
and you will also need 3 extra M5 bolts and 2 nuts. one to secure the rail in place (think mine is around 20 mm long) and an extra bolt for the battery case lid (20 mm as well) and the one for the battery holder is 40 to 50 mm long.

and thats it! assembly is fairly simple, but best to follow the steps in the images to assemble the rail, its kinda fiddly
