So I just got a new rf20, and I love it. I really want to mod it though, so i've been looking around at the options. My first question would be, what is the most reliable way to get more power out of the gun, without banding the bladder or anything because I don't want to worry about having it explode. I like the idea of this piston mod:

If anybody has tried it, how well does it work?

My second question has to do with this barrel relocation mod:

I love this mod, but my only concern is that it won't be sturdy enough to pump the gun without worrying about the pump falling off. As you can tell, I'm really worried about messing this gun up, so if anyone has tried either of these mods can you let me know how it went? Thanks

I have a couple barrel materials at my disposal. I have PETG, which is a fairly loose fit and the dart slides in very easily. I also have cpvc, which is an extremely tight fit and I can just barely twist the dart in when I file the inside of the barrel. I know that the looser PETG fit is good for air guns, but should I use the looser PETG on spring guns like my nite finder? The main benefit would be that it would be a lot easier and faster to load if I was using PETG.

I'm gonna simplify things, when a brass tube is 9/16" is that the inside or outside diameter?

I know, I know, why would I do such a thing? Well it just so happens that the rotating system broke, rendering the 6 shots useless. Besides, it looks like it could make a damn sweet loser rifle. Anyway, I was wondering what kind of barrel I should use. What I was thinking was something like a breech crossbow, with a pvc coupler on the gun itself and a barrel with brass nested in pvc, about 10 inches of brass and 8 inches of pvc. Does this make sense, or should I be doing something different?

everyone says they get great ranges on their nf's when they use cpvc, but here's my question: is the dart supposed to fit so tight? the farthest i can get the dart into the barrel still has a little sticking out the end, and that's with a lot of twisting. should the dart be going farther into the barrel, and should it be so difficult to get in? thanks
