Browning BAR MK4 Review (2026): 400 Rounds Through a .30-06
Four hundred rounds through the Browning BAR MK4 without a stoppage, with a best group of 1.12 inches at 100 yards from Winchester 150 grain Power Points. Browning’s own catalog is the problem: it still lists the previous MK3 as current production, in nine chamberings against six, and a trusted retailer sells one for $488 less.
