Basicly this gun is just my 5mm Marker with a blowgun pilot, a fore grip, and a ram rod holder. It gets great proformance for it's size alot better than the origional Marker Gun. Can anybody tell me if 7'' of foam penetration is good?

I liked it better as a marker gun... Oh well.

If my input is anything, I would replace the huge 1/2 inch tee you have there with a 1/4inch brass one. Minimizing pilot volume and adding to the cleanliness of the launcher. For some reason, Brass fittings always make things look nicer.

And what is that foregrip? Doesnt look too comfy. Whatever.

Anyways, I like the overall Idea. Needs work in my opinion.

And yes, that penetration is pretty good for such a small cannon.

The tee is 1/4'' it is what I had on hand see there is a bushing that goes to it that is 1/2'' to 1/4''. The fore grip is for more accuracy with one hand the gun jerks when I press the blowgun due to low frontal weight but when I hold the fore grip the gun stays quite still. The grip is made out of 3/4'' poplar dowel a wood screw and a hose clamp. It is actually quite comfy it fits in my hands great like chucks. I like this gun more than I liked it as a marker because it has a trigger rather than a rod :lol: . I was actually working on a new marker gun that is 6mm that has a push button trigger which can be found on youtube I will post the link.

Well it's not too noticeable but I can tell that it is better. I did a underwater test with this thing. I had aluminum foil over the barrel and a dart in the barrel. I filled the bath tub with water and placed a water filled pop bottle that is capped at one end. I put the gun underwater at the other end and fired.The Dart flew through the water faster than I could see, passed throguh the first side of the pop bottle and stuck in the other side pretty good ehh?

that tee is 1/4 inch? wow, I didnt realize how small that gun really was...

In that case, I guess you really cant do much better..... lol. And it must be fun. Tiny guns are lots of fun.

That 6mm one looks cool. Are you going to do the same thing to it or leave it as is?

I am going to leave that as is. The reason why I changed the 5mm was the broken back epoxy casting and that I needed to pilot it with a rod with the 6mm you pilot it with a cap because I used a union for servicability. Unfourtunatly the back casting on the 6mm is leaking too :lol:

The gun is just 8 3/4'' long without the ramrod in place
Ok, that's smaller than I thought. Actually, less than my hand span.

Not bad performance for such a small cannon either.
