Soon to come an AR-15 clone known as the MKA 1919. Its a 12 guage that comes with two magazines, one in the 2.75 and 3" length.
Its being imported by RAA and the price is around 700 for the black gun and 800 for a camoflaged version.
It comes with interchangable chokes as is compatible with the WinChoke.
It looks promising enough that I will own one and I will shortbarrel it,put a collapsible stock on it and make it look "tacticool." It wont be long until aftermarket items like extended mags show up.
This gun looks like it has lots of potential.
