DC,
I forgot to mention something else about the B2000 that I found out the hard way. DO NOT let the bolt slam forward without the barrel mounted in the receiver. The cocking handle on the bolt will ding up the forward end of your ejection port if you do. If you want to release the bolt when cleaning, etc. without the barrel installed, ease it forward while controlling the forward motion. I found this out on my first B2000. My 2nd one didn't suffer any dings. Hope this helps. Good luck.
