Army Chief,
Actually they didn't anticipate a market. The Irish VFG was user driven, by a particular organization that found it useful for their breaching guns.
They did the initial chopping/ gluing.
When thet showed it to Jeff Cahill he mod'd existing ones for that contract.
Eventually he will have a new mold, but for now it is cut and glue.
I don't choke the chicken, and have been teaching the high hand hold for a few days, so this fits the doctrine.
It is a compromise. You lose space (i keep a complete bolt in there) for a shorter grip. While less likely to catch on anything, that ammunition feed device hangs lower then the chubby.
It is an option- nothing more, nothing less.
Just my $2.00.
