Time to get the mythbusters! is all I can say...

I think the spears are carefully engineered to be hydrodynamic... so I would try to make that leadball into like an arrow or something. I dunno just suggesting

1. As stated, 6mm as close as possible, if you want to spend some extra cash buy a tight bore 6.02mm barrel that is at least 8 inches if you want some decent power. If you want to get something cheap use brakeline that is 5/16". Tightbore is better but less cost efficient where as brakeline is the o...

Umm, I've never really used a CO2 tank before but what I've seen been used is CO2 Tank 8-20oz regulated at 120psi. I'm assuming your using airsoft 6mm rounds.

Any chance you could stick up a video?

If you see bloody it's because it is Australia culture... I doubt anyone will be particularly offended by the use of the word bloody. I wasn't being entirely serious when I put it on my list. Well I'm sorry for being uptight then. A tad tired with 4 all nighters in a row attempting to finish 2 assi...

Blah I'll stop it's just the media brainwashing my mind. i'll like change my recent posts .

If you see bloody it's because it is Australia culture... you can't change that o.O

Edit: Wow! another kablamo production by stephen holidays... your making me more and more bloody inspired grawr!! I'm totally going work much harder on my guns now XD.

Edit: There I've changed it o.O I shall do so with my other posts i can think of

When I saw this MP5 destroyed on my prototype I cried .

This is another beautiful BBMG by Stephen Holidays... it looks so bloody realistic too! U've just like totally inspired me to actually attempt to make my guns look real... cept my construction skills are pretty dim but it's a good inspiration.

First post! I hope... Now that jizz in my pants material! You know what, you remind me of the terminator! Have you shot it yet... any recoil cause that would be awesome XD. What type of air release are you using like piston? sprinkler? Can't tell cause I've never really made an advance air gun before.

LOL did you get that from arniesairsoft.co.uk?

Hmm I'm not very good without visuals though... I'm that kind of person... it helps me understand the mechanism but I want to know what the mech is like.

Hi guys, Its been a while since I've started a topic on this forums because of the workload i got on my final year of school... But I'll cut straight to the point. Does anyone have a diagram of a NON-blowback airsoft pistol and how it would work. I've seen a GAS-blowback before on a diagram. I've be...

Have you tested both pistons under the same conditions where the variable is the different piston. When I watched you video I finally knew the meaning of "pilot valve". So did you used the same barrel, same ammunition and same pilot valve of 1/2" piston? Because I'd assume that the ball valve would ...

Hey! Wait a minute... Aren't you McRedRooster on Youtube? Because I just realised that you piston is very similar to that of on youtube.

If you are I'm planning to make one of your piston guns .

Wow... That is awesome! You gotta film piston vs. piston... it'll be even more convincing... I might actually copy your idea if you don't mind XD.... I'll start with hot glue first though since well... never built a piston in my life lol. Edit: Oops wait now I get it! More volume for and SA what eve...

Dude... it doesn't look ghetto at all... You asked him to use PVC pipes and he used it!... Oh oh... there is electrical tape on it... it must be ghetto!... it's not. It's probably just cheaper to use tape. Give him a break man.

I think it's great! Is that pressure rated pipe btw?

Wow! Nice find!

I've been wanting to make a piston valve cannon but I was too noob to find any information on it o.O

Thanks dude!... After I finish my ball valve cannon I'll work on this
