I agree with Pettifogger 100%, he is spot on with that opinion.
The only time I have bought new nipples for my ROA's is when I considered that they were getting eroded and causing back-blast.
This could have just been a fancy of mine but it did bring me a certain amount of peace of mind when in competition.
( I was heavily into bullseye (precision) comps at the time, a whole different mind-game).

I have always replaced with Ruger nipples because I don't know of any supplier of Treso's in the UK,,,if anyone over here does know of one, I would appreciate the info.
