This page preserves the XS-B40 hub from the original KermitAirgunClub.com, a Kermit, Texas airgun club site active until it went offline. The original page linked to dozens of outside resources and forum threads; we checked every one individually before republishing this list, most had gone offline entirely, so only the ones still genuinely live and on-topic are included below. If you're an original contributor and would like something removed or credited differently, contact info@airgunguide.com.
