10,000 units?
I beg to disagree.
Even the CSA VZ58 and CZ858's together don't have those numbers.
IF it's 2500-ish bucks and IF it's non-restricted they MAY sell 1000-2000 units.
Which is still infinitely more than the police/LE and Mil. end-users would purchase, as the G36 has been available to them for over a decade now.
If Nicholls is the distributor, we're likely to see very little imported at a time (aside from maybe a decent initial batch order). HOWEVER, when I spoke with the Nicholls/FN Sports rep back when I worked at a gun shop, he did say they were already planning on getting one into the RCMP for FRT verification, with the hopes of a N/R status. That was obviously before the turmoil, but they were already planning on the FRT for it.
You better check your math on the CZ-858 family of firearms. Well north of 10,000 have been imported and sold. Marketed properly, with a decent distributor, and keep the mark-up reasonable, the HK could sell like hotcakes and displace rifles like the XCR and potentially fill the void left by the Swiss Arms.
