thanks guys i think ill go with bc arms

well what other kind of ignition system could i use?

the fitting for the cap?

can this be done on the screw in cap?

ok so i have my combustion chamber and barrel assbly all complete now to install the bbq igniter. i was hoping someone could give me step by step instructions on how to do this right so i can fire my cannon safely

i did take a look but the fitting is about 90 dollars and a 5 ft piece of pipe was 25

where can i get a hold of thid odd size. im looking to build a tennis ball cannon so i need a piece of 2.5 inch pvc or abs and a reducer coupling to 2 inch pvc or abs. so if anyone knows where i can find this pipe for relatively cheap please let me know
