botton loading knex rifle help
I'm trying to build a rifle based on the KRISS sub-machine gun
But I'm having trouble building botto-loading magazine (hopper)
Obviously, gravity will not do the job...
I have tried adding a rubber band to pull the rounds (white rods) up, but it ends up making it quite difficult and time consuming to load since you need to try to pull the band back and then load.
My magazine is based off of this design
I have tried adding in a little bolt to pull back the elastic, but it is very difficult due to the small width of the magazine (I am very attached to using white rods)
Can someone make any suggestions, or explain to me how their's work?
