Hello, this is my working knex version of the M4 Carbine. I have seen a lot M4's on 'ibles, and I decided to make one by myself.
I think my version looks pretty good, and the range is 35 feet without front barrel and dark grey connectors as bullets and 40 feet with front barrel with red rods as bullets.
The barrel is from the UMP-45, the removable magazine mechanism too, but I made it even better.
I've built iron sights because I think they're btter than scoops.
Maybe I'll post the instructions but I don't think I've plenty of time.
PLEASE NOTE: You can't use small dark grey connectors as bullets while the front barrel is connected to the gun.
Great working magazine system
High piece count
The bendy blue rods (handel) can snap out frequently
