It looks like it is too much material to add weight to the gun. Also, it is not going to release heat as well as the current guard. It looks like JP Rifles at the bottom. Not a fan...
I am not a fan of the new look. The old design is MUCH better looking. Might be time to go back to the drawing board on this one as it seems like a step back in design quality. Maybe stick with the current design but leaving the bottom not completely cut through. The new lines do not flow at all. But we don't purchase GAP weapons because they look cool. We buy them cause they SHOOT and SHOOT good !
