Hey All!

I've been lurking here for a while, ever since I decided to make my own marble-shooting air rifle a year and a half ago. I finally got around to taking some videos/photos and writing it up. Here's the page on my site:

It works nicely, even after one and a half years, and I think overall is a pretty sweet package. Let me know what you think!

Sweet looking and clean design! Nice to see somebody who doesn't "rice" their cannons as much. :p

Good job and welcome to the forums!

I'm quite happy with the sights aswell! It must have taken me an hour to fiddle the pin into the correct position (straight, centered) in the rubber gasket after cutting it to shape.

The dimensions (length, height, butt-to-grip distance) are basically the same as an M16 assault rifle, and it feels really sweet to hold. Not going to take any pictures posing with it, slightly too illegal and may send the wrong message!

What does "rice" mean?

Uh, no. Rice means pointless cosmetic additions which detract from functionality. I was complimenting him on his lack of rice.
