ARES L1A1 Inner Barrel Length

[Mausturm]

Hi all,

I want to work on an L1A1 from ARES and was curious about the Inner Barrel length so I can purchase an inner barrel of the appropriate length. From what I've read, the ARES L1A1 has an inner barrel length of 560mm, but unable to confirm either through ARES website, or otherwise.

Does anyone know the appropriate barrel length of an ARES L1A1 without having to resort to cutting down a barrel?

Thanks,
