Description
This is a desktop sized fully functional Scar-h. With moving bolt, rear stock, magazine, and sights.
I will be updating this with a different option for the handle on the bolt. More details shortly.
There are 2 magazines, one is for a friction fit and has a spring latch to hold it in to the mag well. The other has a circular cut for a magnet, that can be glued into it and can stick to the bolt used to hold the rear mount on.
Items Needed:
Qty 2, M3 bolts M3 x12mm. One for each the stock mount and hinge.
M3 bolt handle, for the Scar Bolt. M3x 4mm to 8mm, either is fine.
1 light spring 1 inch in length. A pen spring should be fine.
Build Instructions:
Print everything with the best orientation for your printer. To build the stock you will need a m3 tap or drill out the hole with a 2.5 or 3mm bit. Then tap the holes in the rear mount that the stock connects to. Tap the hole in the stock, and then the one on the bottom of the main body above the hand grip. The bolt will need an M3 bolt in order to cock the gun. So tap the hole in the bolt. Then slide it into the main body and screw in the M3 bolt. Slide the spring in behind it, then attach the rear mount and screw it in. Connect everything and do a test fit.
Then take the stock latch and test to see if it connects. File or sand if needed. Put a tiny amount of super glue on the tab that fits in the stock. Leave no glue on where it connects to the rear mount, so its able to move and flex. Once its dry test for function.
You can see the image below for how they connect.
