<div align="center">The Antimaterial Cannon</div>

Finally took some pics and finished the description page (lots of info on it: AMC homepage).
Here's the AMC in all its glory:

Image

* A - Mini bike pump
* B - Scope
* C - Flashlight
* D - 29mm barrel
* E - Bipod
* F - 18mm barrel
* G - 13mm barrel
* H - Blowgun
* I - Butane spray

And some more shots:

Features:
Breech loading, electronic ignition, laser pointer, 2.5X scope, foldable bipod, onboard flashlight and security lock.
There's no point in copying the information that's already on the description page. There are some news I haven't included on the page: I've recently tested it for power and it drives 4mm nails in wooden planks. It also shoots AA batteries and—obviously—pre-cut spuds. Standard ammunition is currently being developed.
Hope to add a video in the next 2 weeks.
Feel free to post questions but please nothing stupid like "What's the pump for if it's a combustion?" It's all on the description page.

My compliments!
I don't really like combustion guns but I can certainly appreciate this one.

That's freaking beautiful! I've never actually seen one with a scope. It would be awesome with a bolt. (If it has one sorry)

Thank you for your kind words.
@schmanman: Why, are you with the Police? :lol: I live in Romania.
I don't know how legal these things are over here, so until I do, I'm keeping a low profile.
@Atlantis: It's somewhat bolt-action (it opens and locks the same way), but the barrel comes off entirely. I decided to make it like that because the 18mm and 13mm barrels slide in through the breech. It would be easier to understand if I had made a video, but I don't have a camera available yet.

For what is the bike pomp?
My little experiance tells me that the combustions aren't good for snipers.They can't fire heavy things like a funnel with a nail.

why not? an accuratly metered propane cannon can fire a 100 gram "spud slug" at over 400 mph, thats over half the speed of sound at sea level with some decimal points attached

The combustions are only powerfull with a wide barrel.No matter what chamber and projectile you use you can't do much damage with a combustion unless the barrel is wide.

1st of all :lol: :

Second: On the contrary, my fellow European. The 18mm barrel works a lot better than the 29mm, even tho' the C:B ratio is close to 1 with both barrels.
And I've shot heavy projectiles such as nails and batteries with impressive results.
If the funnel is very long (like as long as the barel), the air inside it acts like a buffer (or spring), absorbing some of the power. You should try sealing the end with styrofoam or something.

No, all the barrels are PVC. We have different standards over here, so I can only estimate wall thickness: for the 29mm - about 1.2mm thick, the 18mm - about 2mm thick and for the 13mm, only about 0.8mm and very flexible, but it seems to hold just fine. If it did explode, I'd be protected by the outer 29mm barrel anyway. I'm not worried about the bigger ones, since the 18mm is sleeved with a steel pipe at the breech and the 29mm with two layers of PET.

thats because your cannon must rely on projectile weight instead of velocity

if you made a cannon that shot as efficent as your mini stuff it would bl0w your mind, i blast spuds through 1/2" plywood dude, D size batteries will dent and sometimes make a tear into the sheet metal of a car door.

your small cannons shoot tough because you are using projectiles with a low weight, try shooting a 300 gram slug in a 2" barrel with a pneumatic cannon (with modded sprinkler valve) or a combustion with accurate metering device, you'll love the results
