Well so far, the most i can get is 120 psi but as soon as i can get my shock pump done (which sadly wont be for two more weeks), then ill have 300 psi +.

What kind of fill port is on that? Schrader or Male quick release coupling? It looks to be a coupling, but I'm not sure.

@LikimysCrotchus5 hey that's a really nice gun... can't wait to see some dammgae pics... do you plan to use marbles ?
BTW before you take that to 300+ psi make sure that the hose can handle it... it seems to me that it is rather weak

Yea i think im gonna change the hose, so can anyone tell me where i can get some good pressure rated hose?
If not, then ill just completely take off the hose and it should be ok.
For ammo, i use crab apples, they just grow off the tree i have in the front yard but i am soon gonna be using ammo like pykrete slugs and epoxy too probably.

Some new mods I see. The gage pic stinks and I'm not sure I would fool with the safety ball valve, but it's a usable option...just places the blow gun a little low.
Otherwise I like seeing you progress the cannon forward. It has all the trappings of good performance for its size and caliber.

Thank you starman..
I do agree with the trigger but since safety is always a concern, ill just have to keep it on.

Maybe you could give some thought to some kind if reconfiguration if you want to leave it...a way to get the blow gun better placed. It's not that big a deal, just being picky tonight.... 8)

Yea i see what you mean, aesthetics over safety.
No but really it doesnt bother me (yet).
If i feel like it, ill play around with it

Well I believe there's usually room for both...

Looking good!
Some options for the hose might be, regular compressor hose (300psi rated) or hydraulic hose (rated at more than you will ever pump to

)
Awaiting the damage pics.
