The C4.1 Lego Semi-Automatic Crossbow


Introduction: The C4.1 Lego Semi-Automatic Crossbow

The C4.1 Semi-Automatic Crossbow features a few improvements over the original C4, such as:

-Capacity has been increased from 4 rounds to 6 rounds
-Magazine cover has been improved to be more sturdy
-Trigger handle has been changed to be more comfortable
-A stock has been added.



The crossbow's range is still 35+ feet, and it is still powerful and accurate.

Step 1: The Stock

This step will build the stock of the gun.

Step 2: The Rear Cover/Stock Attachment Area/Rear Sight

This step builds this part of the gun.

Step 3: The Trigger Handle

This step rebuilds the handle.

Step 4: Magazine Cover

This step rebuilds the cover which goes over the magazine area (where the rounds come out).

Step 5: Magazine Adjustments

This step slightly lengthens the magazine, to support the extra 2 rounds. The total magazine capacity 6 rounds. (As well as the 18 necessary rubberbands to fire them, see the rubberbands sections in the original C4 Crossbow Instructable).

Step 6: Assembly of Parts

This step will assembly the main body with the handle and stock.

    hay guys check out my new lego crossbow click on my profile come on do it for master chief

    bof! la natasion escargo la macheti sorry i acsidently tiped in french

    Instead of three rubber bands linked together, I used four single large rubber bands that are fairly tight. It easily shoots through paper and leaves pefectly rectangular holes. Another reason I did this was because with weaker rubber bands the last two shots can jam, this is because the bands on there own don't always pull the gear around properly.
