metal vs. plastic nozzles
 

just out of curiosity, I was wondering what ya'lls opinion was on metal vs. plastic nozzles, would the metal cause more stress? I have not had any problems w/t the plastic. so when or under what circumstances would you upgrade to a metal nozzle?
thanks.

Plastic nozzles can break from time to time say if there is a jam in the hopup bad enough and the nozzle slams into it. A metal nozzle will be far less likely to break but then instead of it breaking it might damage your hopup if there is a jam. Also some metal nozzles are known to dent or imprint the BB's when it strikes them which effects their flight path and stability. Also there are differences between aluminum and steel nozzles, not sure what the effects are exactly between those two though.

I've never actually seen a nozzle break - usually when a jam occurs, it's the tappet plate that breaks (right where the nozzle mounts). I am unsure as to why folks would use a metal nozzle as opposed to a delrin/poly one.

i have repaired a gun with a nozzle break it was a bore up and was actuly broken where it sit on the tappet plate, but its still not a break wee see often.I think people would use them for the sound it give, if you use them with metal piston and the head with a novesk flash hider might give someting interesting (loud sounding).

Team mate of mine had a nozzle snap in half at border wars in his TM M14, caused by a jam. Personally I'm a fan of plastic and would prefer to have that in the PTW cylinders as opposed to steel *shudder*
