Roko, is it a TM or JG 552? Just to make sure: The 552 has a 247mm inner barrel, and with a 590mm inner barrel your silencer will have to stick out 343mm in front of your barrel to cover it. Maybe you were thinking about a 509 barrel? It will of course be easy to break, since the silencer's only attached to the outer barrel. For such a length I'm skeptical at best. For airsoft I don't think you really need such a long barrel for such a weapon anyway. Maybe get 247-400mm Tanio Koba twisted barrel instead? Of course this is just me thinking out loud, and you must of course do what you want

Just make sure to get a less vented, or maybe even unvented cylinder for your gun if you're going with such a long barrel!

As for rails you can get a china-made one for 1/4th of the price of the Proud one. eBayBanned seems to be selling one in the near future, and you can already get one at ehobby asia for about $50+shipping. If you look at pictures of 552s with the rail mounted, you will see that it's very close to the same height as the stock handguard. You might be able to get some more vertical space by removing the battery holder. As far as I see, it's not a part of the "outer barrel" and thus only works for positioning the battery. Maybe you're lucky enough to get some more room, but you will not be able to fit a longer battery, as it's still limited by the upper receiver and not the handguard (if it's a TM style SIG anyways). My suggestion would be a 7.4v mini-size lipo battery. In the normal handguard it's a very tight fit, but not impossible when you remove the battery holder. A 7.4 lipo will provide you with a performance close to a 9.6 NI-CD/NI-MH convetional battery due to it's superior discharge rate.

PS. I wonder if the china-made ones are clones of the Proud rail.
