Systema New Bore Up Cylinder Set

[[]D[][]\/[][]D]

Does anybody know if the Systema New Bore Up Cylinder Set for the Marui SIG 550 is compatible with my Marui SIG 552 SEALs?

[ILLusion]

From what I recall, it's not compatible. The 552 uses a short cylinderhead nozzle, like the one the AK-47 uses. There's a possibility I could be wrong on this.

I don't know about the compatibility of the 552 and 550 air nozzle, but I have a strong feeling that they won't match.

My recommendation? The 552 is not meant to be a gun that can support such a huge inner barrel and/or such high velocity. You don't really have a need for a bore up kit in it.

I'm planning on getting a 551 inner barrel and covering it up with a silencer for my 552? Do you think that the bore up set still won't be compatible with it? If it's just the air seal nozzle that's not compatible, which Systema air seal nozzle is compatible with my 552?

[ILLusion]

It still won't be compatible. Changing the inner barrel makes no difference to the mating with the air seal nozzle.

Systema doesn't make an air seal nozzle for a 552.

You don't need a bore up kit for a 551 inner barrel - you just need an unported or type 0 cylinder.

OK, so how about if I get a Systema Type 0 Cylinder, and Systema Silent head set, would that be good?

[ILLusion]

That'd be fine. Just make sure you get the regular v3 silent head set.
