Why the $700 price difference between the Canadian TAR-21 and the US SAR-21?
Ah so many similar questions . . .
Here! Try this!
The best way to think of it now is that there are four kinds of Tavors available in Canada.
Gen 1 was imported by Canada ammo, and came with a Mepro 21 optic clamped to the barrel. Some 15" IDF CTAR barrels also came in during this time period. Looks like this:
The Gen 1.5 was a $300 upgrade available for the last two Can-Am batches of Tavors. Gen 1.5 is identical in every way, except that it included a factory pica-tinny rail and its Mepro 21 was quick detach. Many people with Gen 1 Tavors have converted them to Gen 1.5 to allow for more optics than just the Meprolight. Looks like this:
Gen 2 Tavors were brought in by North Sylva, and feature a full flattop rail.
Most of these have integral BUIS and often come with some unusual iron sights off the shelf. These units use a lighter polymer body and have a different texture than the Gen 1 and 1.5 models.
IWI US Tavors have been imported by IrunGuns, although I've never seen one on Canadian soil. These units come with 16" or 18" barrels. They are restricted, feature a lighter trigger, and have QD sling mounts in the hand guard and rear receiver. They are a flattop with integral BUIS, and have a body that is
very similar to the Gen 2. Looks like this:
All Canadian Tavors are under the TAR-21 model name. The IWI US Tavors are called SAR-21s, on account of their unique trigger pack and receiver insert. The IWI US Tavors seem to be compatible in terms of barrels with Canadian Tavors, but BCG and trigger packs are certainly not.
