It is difficult to get OLY AR stuff here in Canuckistan. OLY used to have a Canadian presence, but not much lately. So, OLY stuff is basically UNOBTAINIUM up here, unless you stop by the Puyallup Wa gun show. Sometimes a few of the OLY employees have a booth there. This is NOT an official OLY sponsored booth .... just some of the OLY guys selling OLY stuff in their spare time.
I've built a few dozen ARs from OLY parts kits, including a few VERY accurate target grade rifles with some of the OLY high end barrels ...eg" SS FLUTED. They shot well enough, but were VERY tightly chambered, and required a few hundred rounds of break in before becoming totally reliable.
of course,
as always,
