We have started making Remington 28ga magazine extensions (BLUED). Rem. 28ga +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. 28ga +5 comes with magazine tube, spring, shell follower, and base clamp (sling swivel loop pictured is no longer included).
