hmm, on suggestion of somebody else on Arnieairsoft, they said that I could locktite it....so in my case, I have indeed reinstalled that roller, but the pin locktited, so it doesnt roll lossely anymore....
I quote: "The round thing is a roller so it would reduce wear against the bolt. It's meant to be free rolling but you can apply locktite on the pin that holds it."
is this bad?
edit: I indeed did not read your message

Okay, so you have already received your new ratech hammer? or are you using a replacement bearing?
Is this the ra tech hammer you are talking about?

I might get that replacement too I guess.
About the trigger issues, I have not got any trigger issues now

I spraid a shitload of silicon oil everywere, and the trigger responds as it should now....And I have already installed the ra tech firing pin and valve locker btw.
My main returning issue is still that bb's are filling up inside the barrel.
But as I said, I will make some single shots attempts this evening, and see what will happen...
