That non standard shelf and the carrier block is why I'm not getting one of the new ones. I've been picking up older IGF guns that seem to being sold below cost in the panic resulting from his meltdown. In the day his work was second to none. The ones I have were rolled on Turkish flats and the welds are prettier than even my older HK. Just a thought for all of you. They all came with fa carriers, no blocks of any kind and a HK spec semi shelf which is useful to me as a 07/02.
