The TacStar SideSaddle Shell Carrier, 4-shot, for the Mossberg 500/590 in 12 gauge (brand part no. 1081167) mounts a spare-shell reserve directly to the receiver so a shooter can reload without reaching for a separate belt or stock carrier. Made by TacStar, the carrier’s aluminum mounting plate attaches using the shotgun’s existing pin and screw holes, so no permanent alteration or gunsmithing is required. A lightweight molded nylon shell holder keeps four rounds of 12 gauge ammunition ready and within easy reach for a home-defense or duty shotgun.
