This is my most powerful crossbow EVER!!! It can chuck 1X6 Lego bricks up to 60 feet! It's powerful too. The 650X can punch through a sheet of paper fold in half twice! It's about the size of a real crossbow. (Mabye a tad smaller) I had a lot of fun build this. If you want to try, remember to be careful, and NEVER shoot it at, say, your sister. (I know the temptation is strong, but please resist it.) Mabye your sister's doll. Blast away. Thanks for reading, and don't forget to comment!
