We have started making Remington 410 magazine extensions (MATTE). Rem 410 +5 makes your shotgun a 10 shot (9 in the tube 1 in the chamber). These Extensions are custom made to order. When ordering allow up to a week before we ship. Rem 410 +5 comes with magazine tube, spring, sleeve insert, tension spring, and base clamp (sling swivel loop pictured is no longer included).
