Depends on exactly what you want from it. I've fired 230g (~.5 lbm) projectiles from a 20mm air cannon at ~65m/s (~215 fps), which is visually impressive from the perspective that, even properly shouldered and fully braced, it'll shove you back several inches. (This in itself presents a possible ri...

I decided a little while ago that I would push the envelop a bit and see exactly how heavy of a round I could shoot out of my larger air cannon. It turns out what I ended up making was probably the heaviest bullet I could make weighing 12,600 grains or 1.8 pounds. The round consist of a mild steel o...

I posted a while ago about the rifle I converted using the GHK GBB conversion kit. I got a few comments asking me if I knew a way to fix the feeding issues that they saw in one of my videos of it. I was under the impression that the issues were isolated to my gun. However apparently its a problem ma...

Most of the time when you are building an air cannon you want some way of firing it from the pull of a trigger. There are tons of ways this can be done but the problem with most of the ways I have seen it done is the fact that it restricts the air flow so much that you get pretty crummy performance ...

I have just recently converted one of my air soft AEG to use green gas/propane and the magazines could be modified to use HPA. This was an incredibly easy conversion because of a really cool kit produced by GHK. It is a GBB "gear box" so to speak. It is basically GBB internals that have been squeeze...

There are many things that you could possibly think of to put in an air cannon. I have put quite a few odd things in some of mine and have many videos on the subject. Play list here: https://www.youtube.com/playlist?list=PLoubJPvjc72areqD_ASbD9DzjOXMGpz9a However I think it might be a good idea to d...

Most likely because my channel is not that old and not popular at all.

I wanted to share a project of mine that has been the subject of my YouTube channel for a while. I had the idea several years ago to make a shot gun that is powered off compressed air that uses regular spent 20ga shells after picking up many at the range. This has ended up being the star of the chan...
