Probably SIG-Sauer realizes that the US market would not react well
to an AR brought from outside
(remember the initial reaction to the HK416/7).
SIG-Sauer has little to do with SIG
and almost nothing to do with Swiss Arms.
Officially they didn't say about price yet,
but I think it can't be much (in US), given the abundance of AR's.
In US, prices started to drop for complete guns
and they will continue to drop.
