I had a Historic Arms Bren for several years, extra barrel, case of mags, two butt stocks, 7.62x54R kit with different mags and barrel. It worked fine and ran flawless, never bound up or had issues of any kind with commercial ammo, a few issues with old milsurp ammo and hard primers. If it does not run without binding up, it is not a $6k rifle in any market.
