I have very rare discontinued Haenel CR223 10.5" pistol which won competition agains HK for new contract rifle for Bundeswehr, but saddenly lost patents against HK. It's a piston operated gas system Ar with chromed bolt (bolt  and bcg completely interchangeable with HK). Hand grip was replaced on HK (since originally it's came with very skinny B&T grip. This Haenel was imported in US under B&T). 
It's also came with surefire three prong SOCOM flashier/compensator ( thread exact the same as on HK, metric and it's hard to find this flashhider in stock). Come with iron sights MI and rail covers. This Haenel from first batch and came with keymod handguard. 
put through only 200-300 rounds. 
Asking $3500 firm flashlight not included
