Intro: The Lego C3.1 Shotgun-Crossbow
-improved, more realistic stock (the actual shoulder rest on the back of the stock can bend for added comfort)
-a shotgun sight (approximately showing where fragments will go)
-a shotgun firing runway (gradually widens to allow shell to seperate more horizontally)
NOTE THAT IF YOU HAVE NOT ALREADY BUILT THE C3 CROSSBOW, YOU NEED TO GO TO MY OTHER INSTRUCTABLE TO BUILD IT: https://www.instructables.com/id/The_C3_Crossbow/ THIS INSTRUCTABLE REQUIRES YOU TO HAVE ALREADY BUILT THE C3, BECAUSE THESE ARE THE IMPROVEMENTS.

Step 1: Runway Changes
Basically, jbefore starting this step, take off all the flats and thin pieces on top, so that the run way is only a TOTAL of 1 and 1/3 bricks thick in the MIDDLE of the runway. Then, start with pic 1.
Step 2: New Adjustable Stock
A simple stock, with an bending back piece. Pieces need to be taken out of the back of the crossbow first though, before the actual stock is built.
Step 3: The Shotgun Sight
Basically, 2 short tactical rails, and a piece in the middle to make longer shots with.
Step 4: Y1 Shotgun Shell
Basically a large piece with 5 pieces attached underneath, when the rb(s) hits it, they hit the smaller pieces, which seperate and fire out, along with the larger piece. The runway is like that because then the shell can seperate more horizontally, not just vertically.
