Range: terrible rounds aerodynamically, but pretty good gun to fire them with. it pushes them for 40ft but at close range it's pretty accurate. needless to say I'll be posting a v2 soon
efficiency firing: not that good, but better than many slingshots. pull the bands back over the catch, then pull back and release the bolt to chamber a round. really cool mech :)
comfort: a little short from stock to handle for my taste, but will fit many quite well. everything else really comfy.
mag: modified version of my zipdart mag. works pretty well and loads straight in, not swivel in.
looks: I like to think it looks cool but you decide. I'll start work on a v2 soon and hopefully post instructions with that
