Nah it's CA so there's no tray with it, I literally need about an extra 3mm more for it to fit over the standard handguard so hopefully the ris will help.

Currently using a 7.4 Lipo in my 552 but have brought a mini 9.9 LiFe which is the same size but slightly thicker than a mini 8.4 nimh. As most Sig owners know battery space is an issue but does anyone know if fitting the Well RIS or other types will give me a little bit more room for the LiFe to fit?

Before the I had the new spring/piston guide I was only getting 300fps and 13rps with 8.4v nimh.

Right im currently running a pretty much standard internals in my gearbox apart from poly piston + bearing spring/piston guides on what I believe is a m90 spring that came with the gun. (ca Sig 552) With this and a 7.4 30c Lipo on dean's I'm getting a constant 330fps with an rof of 16rps. I am wanting to up my rof to around 25 max but would like to maintain or even up the fps to 350 but without getting a bigger battery. I know I will need to short stroke the piston a bit but I wanted to know roughly how much would I need to on a 14 tooth piston? As I wanted to upgrade to a m110 spring. Obviously a high torque motor will be required also 😊

Cheers for the welcomes guys 😉 Adam3088 iv not used my Sig at 39 yet as only been twice lol, I'm bringing it to cbq tomorrow actually to get it chrono.

New to the forum and airsoft in general, I play at bunker 39 in Colchester, just thought I'd say hello 😁
