I'm looking at a BLR-81 and wanted to know a few things. 1. Are they hard to clean? I have read that you can't disassemble them like a Marlin. 2. Are there any issues after a few hundred rounds? 3. Is it really THAT hard to find a gunsmith to do any necessary work? 4. Are extra mags available at a "reasonable"(>$75) price? 5. Are larger capacity mags available? I know, it's a hunting arm, but well; they make a 10 rounder for the pump Remington rifles. Just sayin'. 6. It's used, so what should I specifically look for? Thanks!
