10.5″ Australian Automatic Arms SAC at 300m with Holosun 503

In which Mike takes his Australian Automatic Arms SAC in .223 Rem / 5.56x45mm out to 300m with a Holosun 503 atop it to zero it and to see what it can do.

Here at BotR we show things as we find them, warts and all, so you’re seeing this more or less as Mike did, with all its frustration…

The AAA SAC is kinda the last version of the Leader T2 Mk. 5 (aside from the Bushmaster M17S bullpup and the new K&M Aerospace version which is closer to the Leader), and is a real sweetie. But something’s not quite right in that particular Holosun or the rail.
