Not trying to nitpick (after all you didn't choose the name), but how exactly does a muzzle device constitute it being an "AK".An AR/AK is a 14.5" Hbar carbine with the AK 74 comp pinned and welded on it from factory. Its chambered in 5.56 nato. Also they changed the name in their product catalog its now the Bushmaster AK.
True, why am I trying logic with a company that markets a bullpup, which was based upon the Australian Armstech/Edenpine C60R bullpup (designed for, but not accepted by the AU military), which was it turn based upon the AR-18, as the M17S. Oh well, at least it is an excellent rifle...I dont know either? Its a Bushmaster thing I guess.
It appears to be the same as a Sightmark. Be aware that the Hakko is a airsoft component, but if it works, it works.If anyone know where I can get another one of these let me know!
