ITS Good but d handle goes SNAP every time I pull the trigger

ITS NOT A SEMI_AUTO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!:(

Its cool xept it aint able to shoot a green rod; I added 2 more blaks instead of those blue connectors............ THey don't even connect stuff!!!!!!!!111

Not a semi auto but good for a 2nd instructable.

Even though it looks like it has true trigger this isn't semi auto. When people do K'nex, they want something better than some nerf gun or this'd be an all nerf gun site. This isn't much better than a maveric with a clip (or whatever gun has those) so I'd say its not worth posting in K'nex. 3/5 stars for me

If you wanna make a semi auto use my concept.............. serisouly just try to add a hopper to my pistol if you rly want to ............................................

Sorry,'s not semi-auto. This is magazine fed single shot. Oh well, looks really cool! 4*.

Isn't that a hopper?

Technically, you're right.

 Lol all comments over semi-automatic stuff
