G'day,

These are the instructions for the lever action RBG I posted a little while ago.
For more photos of the gun, you can visit the original post.

General information:
- Lever / hammer mechanism
- Holds four to five rubberbands
- Stock can be customized, as it doesn't house a single part of the mech
- Comfortable

Lets move on to the instructions, shall we?

Important note:
The blue spacers in the hammer should go on the green rod, not the broken rod. Otherwise, the hammer will be very hard to move. (see last photo)

Green connector, 4 slot - 7
Red connector, 3 slot - 16 (Optional: replace three of them for the metallic variat, for a grey barrel)
Light grey connector, 2 slot - 4

Attaching the Individual Parts

It's the easiest when you detach all the rods connecting the stock with the body, and re-attaching them one by one. Almost done!

Rubberbands

P6050119.JPG
P6050120.JPG
P6050122.JPG

Grab a couple of rubberbands.
One on the trigger
One or two on the hammer
The gun will the performing the best when you have three to four rubberbands on the ratchet. Otherwise, the lever and trigger will be hard to move.

Quick Trigger Fix

So, as mentioned in the comments, the white rod on the trigger can sometimes break off.
This is a quick, little fix that prevents the trigger from going back too far. The trigger pull will be shorter, but a lot easier.

This has worked flawlessly for me, so hopefully it'll be the same for you!

Finished!

If you have followed all the photos, you should now have a functioning lever action rubberband gun on your own!
Tell me what you think in the comments below, and if you build it, be sure to add a photo of it!
