I've got it pretty much figured out but there are two potential slots in the breechface of the subcaliber barrel into which the extractor on the 22 lr. bolt carrier will engage. Which way is "up" on the subcaliber barrel?

What length of hose of what diameter do I need to install over the main recoil spring/rod to keep the kit from hanging up on the hammer? :27000000:
