What this is: 

Makes crosman stock longer so you dont have to bent to it if you are a little bit larger like me. You can also make it even longer by adding spacers between stages 1 and 2. Butt stock is also adjustable in height so you can adjust it to fit your shoulder perfectly.

Nice to combine with adjustable cheek rest.

You will need:

2xM5 screws (flat head) 

• length depends on number of spacers (without them 15mm)
• connect parts 1 and 2

1xM5 screw (hex head) 

• 15mm length (must not exceed 17mm or it will not work)
• connect buttStock to the shiftRail via via adjustWheel and slider

4xM5 hex nuts

• 5 mm high

3x zip ties

• connects part 1 to the crosman stock
• tighten them firmly (to avoid wobble)

Printing:

 It is best to print in orientations as shown on the photo.

After Printing:

• you may need to file down the slot for the adjusting wheel a little bit
• you may also need to put a little bit of hot glue (or something) to the inside of "ears" of prat number 1
