wat is the best way to make a breech barrel?

i dont want my whole barrel to move like the 1 in the 'how to's', how iv gone and done it is i cut a hole for the breech in my barrel but im wondering if i should just put a smaller peice of pvc with o rings at ither end and a small handle on the front end for the piece that seals and opens the breech.

how would you do it?

(this is for a pneumatic cannon)

thanx il try it , it looks like it will work better than mine ,the grenade breech also looks simple but you have to cut grooves in your barrel, i dont want to have to use a new barrel again(i broke the last 1)

another thing ,you can put 50psi in a 2 litre coke bottle,do you think that will fire plastic bb's nicely?
