RE: knight mk85
A word of warning reference the trigger assembly... when you can, remove the trigger assembly off the rifle. Clean it in hot soapy water (I do this each and every time) by swishing it around in the water and running a brush over it.I spray it down with bore scrubber (next trip to town I will get some brake cleaner)which dries it. After that I take an air compressor and blow it clean. If you do not do this, you will end up with a rifle like my friend brought over to me just before deer season. It was a Wolverine and it would not cock. I took it apart and inspected it. The trigger assembly was full of gunk. So I cleaned the trigger up and low and behold the rifle cocked and fired fine.
This is the one thing that I dislike about the Black Diamond XR. I have looked that rifle over and it has pins that hold the trigger assembly together it looks like. I do not like to mess with pins, so I clean it while attached to the barrel.
It is the small minor things, as most will tell you, that makes a rifle not only work time after time, but shoot accurate time after time.
