I had not heard of the Polish version in 7.62mm NATO, I am embarrassed to say (so much for being an "expert") but I would think that it could be an important contender if it is as accurate and controllable as he M240.
I don't believe that the RTD&E folks in the army would even entertain the idea, but I think acquiring some of the Polish guns for comparison testing would be a valuable experiment.
I always had an open mind for examining other countries' weapons against ours: I once acquired a Soviet D-30 howitzer for evaluation for conversion to 5 inch/38 Navy (127mm)ammo instead of the LW 155 for a direct support howitzer for the Marine Corps. Even got to the point of training a Marine crew and getting the weapon and ammo safety approved before I was shut down firmly by higher headquarters..
This gunners mate has thoroughly enjoyed yalls discussion.
Yeah, I’ve always been amazed that politicians and brass politicize the issue of defense procurement by demanding favor towards American gear. If I recall correctly, the MAGs and SAWs used by the DoD are built in the US, just as a loop-hole around the protectionist nonsense!
Cant find much on the UKMs, but this looks nice!
