Like all the Hk series that there will be, this was designed to be portible.I have made the set up comfortible to hold and aim.It is a simple design with lots of added bits and pieces.Who dosn't like bits and pieces.
The specs:
40mm chamber 2 feet long
Hunter sprinkler valve(modified)
20mm barrel
blowgun configuration
adjustible stock
classic duck taped handle
bike tube filling valve
pressure gauge(removible)

The chamber has two elbows one the end and that allows the sprinkler valver and the barrel to be on top of it (U bend). Although it might look like the T piece for the handle is linked to the chamber it isn't, the inside was filed down to slip over the chamber, this was done after I glued the chamber, thats why you can see a link on the chamber just in front of it. The filling valve connects into the chamber on the inside of the 'U bend'. I added an adjustible stock from a bb gun onto the back(it has all the whieghts removed) to make it look better and feel better.

(No Rambo this is not my paintball gun that I was talking about :P )

Feel free to ask about anything.
(special thanks to Benny for help and support)
ps:I loaded my thumbnail but nothing happened

The spinkler valve is very easy to open, all you have to do is unscrew the peice surrounding it and open the diaphram, the modification literally took me 5 minutes. I left the solonoid on it just in case I want to use it.

I took the blowgun and modified it into a 32mm pvc piece, it I want to disconnect it from the silicon tube comming from the sprinkler valve then I pull it off the elbow(it is not fixed but it will not fall off) and uncrew it from the brass pipe connection. It is also rapped in ducktape to give it a nice look.

This is what it looks like when you hold the gun, you can clearly see your pressure. The gun is compact so you have a clear field of view.I am planning to make sights.

This is a close up of the modified sprinkler set up, you can see that I did what needed to be done to tuck away all the guts to make the gun look its best.

After a satisfying build it is always relaxing to stroke your pet rat.

I get it up to 50psi befor the blowgun starts leaking, I think it needs a bigger spring inside or something.

Looks sooo nice, I like the electric tape :D lol

Your jokes are so funny, I think I'm going to put a Tippmann 98 Stock on a coaxial that I will be making soon, and I have some real M4A1 clips that I'm going to mod into it or something :)

you mean he has an AR-15, the M4A1 is the military full auto rifle. my uncle has several hundred magazines for his AR-15, they would just leave them lay on the firing range on base so he would just go by and pick them all up.

My friend has an M4A1 with a silencer and everything (yes, I know it's illegal to have that silencer)

I know it is a true M4A1, but it can't do full auto, he had to mod it or something to bring it home, he was like a 20 year Vet.

I would say super nice to a American builder, but considering your resources and the other out-of-country cannons I have to say, "Damn fine job". Looks very clean, although why didnt butt the fittings together. It doesnt look bad since most are the same distance apart, but why not shorten the connecting peices so they would "butt up"? Nice gun.

When he was cutting his nipples he probably went 3" or 2.5" because that's what some people do by instinct... I always make sure that my fittings are "butting" up to each other because I think it looks better also... I really like how Demon thinks though, it's a cool looking gun...

I'd have to say that American guns are great, they really are, I wish I could own them. I still don't understand why some of you people would live in a place where bears are the top preditor let alone bloody camp there. This is the first proper cannon I have made, I only wish I'd done stuff like this earlyer. My next design is a paintball gun, I am planning to get the components this month.

You can't buy CPVC in South Africa?

You should make one like the Coke Bottle Combustion but with a 3 liter or 2 liter

3/4" CPVC.... with a Quick fix sliding couplings style thing on it from breech loading... That was possibly going to be my next gun on the list, but feel free to make it for me :D
