but as gcw mentioned, your fps might be way above any fps limit, even at an outdoor field.
Also, with a long inner barrel like the falcon, you sort of defeat the purpose of the MP9.
or you could get an angry gun barrel extension with inner barrel (which I have)
I can tell you that it does improve accuracy. The groupings are definitely tighter when I measured at 30ft and 60ft. but... here's the problem. With the MP9, I have to use the CQB bolt to get the FPS under 350. With the CQB bolt, the gun shoots at around 320fps with 0.2gm bbs and around 280~290 with 0.25, which what I mainly use. When I put the Angry gun barrel extension on there, my fps drops to 290fps with 0.2gm bbs and around 250~260fps with 0.25gm bbs. My guess is that with the CQB bolt, it just doesn't have enough air volume for the longer inner barrel, so the fps drops.
However, with the stock bolt + the Angry gun barrel extension, my fps readings were crazy high... like 540fps.... so the moral of the story is.... if you're constantly engaging people at over 100ft.... you may need to get a different gun.
