I had an early Browning Gold, bought new, that wouldnt run even after multiple warranty services. So I bought a used H&K-era Super Black Eagle to replace it. The SBE is butt ugly and balances like a fence post but I have shot it for almost twenty years without a single jamb or malfunction or FTF. When it gets muddy, I just hose it off, run a hair dryer to heat all the metal bits, squirt some Rem Oil, and its good to go. One of my buddies has an M2 (I think) that always gives him trouble.
