Hey metal lovers, the chamber is s\s and the barrel is Aluminium, It can be doubled, up to 2 metres long.
It has a chamber fan and does hella damage.
Evbec can't process the 2 metres but at 1 metre it estimates around 150 feet per second i think with a 25 gram round. It's bloody loud too, with kickback to boot.
Any questions please ask. The barrel is 33mm bore and the internal chamber is approx 90mm x 280mm long.Image

Yet another sweet metal winter type cannon. I will soon be making a mini metal combustion out of iron and brass fittings to add to my arsenal once I get BBQ ignitor.
