This is my first shooting gun I've uploaded. It has a bolt action mechanism (That uses a non-Lego spring). To load it, pull back the bolt, insert the brick, and push the bolt foward. It can shoot up to about 4 meters. It is a little oversized because of the large mechanism, but I like the look of it. Credit goes to Head Shot for the mechanism idea.
Quoting head shot
That looks familiar haha. I'm guessing you got the idea from my bolt action rifle?
I saw your rifle a long time ago (before I had a mocpages account) and built a gun with a similar design. The idea came to me a while ago to build a gun with the same design, but make it better. By then I had forgotten where the idea came from in the first place! So yes, indeed, I did get the idea from your rifle. Most of the credit goes to you for this gun! (Sorry for using your idea, it is a great one). I hope you can understand.
