Beautiful builds! I'm guessing you cut multiple "band slots" to give them maneuverability side to side? Do those guns still float without the shaft? Have you ever had any structural issues with any of those due to the lack of material?
I noticed on some of them you have a handle/trigger guard but the trigger is mounted all the way at the butt and completely exposed. How is it fired? Do you have a safety on them?
Nothing has fallen apart yet. No safeties on the guns I make other than don't load the bands unless you mean it. The picture of the guns with the triggers at the back still on are from works in progress, the triggers have since been removed.
