Here is some more detail for you on the regular version - which is a dam sight prettier than the "Serie Rosso" LE version.
They are priced at £1950, so the other earlier version will probably hang around for a bit while stocks reduce, but I would expect them to eventually go. It looks like the expectation for a regulator has finally come round, and Daystate are giving a lot of people what they have been asking for - and as it's a Huma reg. they have avoided the trap of hashing together some in house rubbish, so it should be spot on. I think this is expensive, but I also think it will be one of the very best sporting rifles out there, and in the real world this is major competition for rifles like the Steyr Hunter 5 etc., not an AA510.
