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.

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.

 ya that sounds like that would work pretty well, but  mine didnt seem to make that mistake with my rbs, so i guess it mustve just been your rbs i guess... although your combo of rbs sounds alot better than mine :)
