i have one! i believe i was one of the first.
technically its not a krink as this sbr has an 11.5" barrel. they call it something else; i call it the khyber shorty. mine looks like it started life as a romy g kit with an added bulgy triangle SF and soup can flash hider. the furniture was done by ironwood designs. had them put russian red furniture on it vs. the black poly furniture.
henderson has a rep for high quality builds and superb CS. this weapon is built solid, with excellent fit and finish.
took 'em took 2 weeks to build it, but another 3 to transfer to my dealer, then another 8 for ATF's approval.
IT RUNS LIKE A CHAMP, and when i have a chance to take a carbine class, this is the one i'll show up with.
these guys were going to take over the market since the fall of vector and the decline of arsenal, but i think they lost their kit source and the AK builds are going on a hiatus.
grab one while you can...
added the Larue/Burris red dot for good measure.
