Re: pilot acs cocking pin..
"piolts have problems with that. if i were u, id get a delrin bolt so i wouldent worry about that. much better quality then stock and it has its own cocking pin."
No it's not. There have been many cases of people losing the cocking pin from the ACS delrin bolt, I'm one of them. I don't know of any specific brand of aftermarket delrin bolt that doesn't use the stock cocking pin, in the top cocking configuration.
