It uses white/silver rods which fit in the magazine but the best anmmo are yellow/brown rods which can be easily loaded in through the end of the barrel.
easy to reload
accurate at short range
stock and handle can be removed for better manouverability
easy to pull apart
can add sights
has places for straps
has a charging handle (just for looks)
It was made using a reference picture from a knex mp5k so it may look something alike but i dont remember whos it was.
I may upload some more pictures and make an instructable if someone wants.

Oh and by the way, im going to start making a new gun in the next few days but i dont know if i should make an assault rifle or a slingshot sniper so if anyone has any suggestions then please feel free to share them. Thanks.
Also these photos were taken with my phone so the quality isnt too good.
