my two new air guns (with videos)

Unread postAuthor: CooperJS » Wed Apr 03, 2013 7:38 am

Hey guys here are my two air guns.

One is a Golf ball cannon and the other is a semi auto marble shooter.

I currently have no pictures of the two air guns but i do have videos of them. The golf ball cannon does have a pvc stock but i took that off before i went to shoot it and make the video and it is also has a 2 inch piston valve.

here are the videos.

Good job, I love the golf ball cannon. However you could increase performance if you cut down on pilot volume.

Yea thats what i was thinking, because it seems to pilot alot of air before it shoots. Thinking of machining up some delrin (i think thats what iv got) to put in the back with some screws holding it down
