Yes to both of those questions. the ram cap is adjustable which really isn't needed imo. I would just stick with the stock style as they usually dont give you any problems. What colors is your ego now? The ccu kits are usually pretty easy to find and the cap usually comes with them, so you might want one anyway to upgrdae the looks. I think I might have a blue one that I could just give you, but it would be a while before I get back to where my gear is.
My is like a olive and has one them upgraded color kits on it....Also i can't thank you enough for helping me out! I came here(techpb) because the lack of help on pbnation =/....ill let u know how it shoots when i replace the o-rings...thanks!
