One of the most interesting guns you will see today. Answered
For those of you who just stalk the forums here, I have a new instructable. The is a single shot but it has a magazine too, so when you run out of magazine ammo, you just load oodammo in the bullet lock! The bullet lock does not need rubber bands, nor does it interfere in anyway with the magazine fed shooting. And it has very strong hop up!
