My nylon 66 has atleast 100k rounds thru it, I've only had to clean it a few times. It eats every thing other then sub sonic and CB caps.
The merkel I traded, work for the gun. The parker was $1500 8 years ago, back in the days when I was working for some one else making 3x what I do now... Anyone that says running a company will make you rich... has never done it.
