Has anybody either ordered or had a chance to see the Tromix R01 conversion built on the .223 frame? From the Tromix site, it has: basic Tromix conversion plus, HK sights, ventilated hand-guard, 14.5" barrel, and permanently mounted phantom flash hider.
The only thing I'm not too sure about is the cutting down of the barrel to 14.5" - what do you gain by doing this - is it just a more convenient size for smaller spaces?
