    Sorry, but I wouldn't call this a sniper. I'd call it a damned fine butt, with a workable gun as an afterthought. I really do like the butt, but after building the rest of it, it was extremely anticlimactic. The pictures were also fairly poor. I had to guess at how may halfcircles were in the barrel, and I'm already running low on them, so it would have been nice to know I could have used two-ways instead. I recommend using a tripod, or alternately, a CAD program. There's an MLCAD (Mike's Lego CAD) program that does K'nex somewhere. It's not perfect, but it'd work for this.

    i know; i was just stating my point ov view. it IS decent; it just doesn't deserve to be put on the list cause it doesn't have a trigger. maybe it was intended as an "add oyur own trigger" kind of gun.

    1) DEAD comment chain 2)The List is/was a list of EVERY crappy block trigger gun on this site. I say it that way because it's true. lock triggers are only acceptable to people who are actually GOOD with k'nex when there is no better way to do the job, and those are usually converted to block-true.

    I think you made the barrel to long. It has no support and just flops around with the tension of the elastics. I went to fire and the bullet couldn't make it all the way through without me having to bend the barrel around. I like the stock though. =)
