Thanks for the input guys. I do have a modify ribbed bucking and I'm building a field setup. It looks like I can get a few r-hops, and put them in my gun and have some extra. I do have a question about R-hop inserts though. I couldn't find any data other than, "Wow, makes my gun shoot farther and more accurate!" and comments like that. Does it really increase range and accuracy that much? Nobody actually says how much further or accurate it makes them and it doesn't even give an estimate. I don't want anything like exact numbers but is it around 20' of extra range or something like 30'-40' extra? My gun does use an M120 spring with a 6.03mm, 300mm barrel and I'm using .25g bb's so I think the r-hop will work in it.
Also spazz, does command post sell R-hops by any chance?
