this is my first propane cannon

My best spud gun story was in 8th grade going into high school as a freshman on freshman Friday Senors would trow water ballons out car windows at us and beat kids up.
But as the car came down the street for us we had a old school with a barbecue lighter and aquanet. they threw one ballon and I caught it in threw it back in the window somehow. I could never do it again but it happened.
So now the car full of wet and angry Senors stops and we run over to the gravel playground.
3 14 year old kids work like a civil war cannon crew one man wadding and loading the barrel with rocks and sticks and shit. Another man staying a heap of hairspray in the back and closing her up. and the third,me aiming and blasting just in time to send a group of charging Senors running back into their car scared.

Lol true story I love potatoguns

That spiral porting on the muzzle though... :D

Looks very good. Any more details on construction, like for the front sight, etc?
