Obviously, the Gunsite 223 in the states was competing against a lot of cheap AR's. This one is after a different market.... I would see this as being a bigger hit here than the states since we dont have AR's. Possible use in 300 blk on Whitetails. Threaded and short barrel, for us a flash hider, for the States a suppressor.
Niche market, and i would see the lack of caliber choices having to do with not wanting to compete against their own product, the Gunsite.
