GG&G Mossberg 590 6-Shot Side Saddle – Black

This GG&G side saddle mounts directly to the left side of Mossberg 590 shotguns, providing secure retention for six additional 12-gauge shells. The elevated carrier design keeps shells clear of the action and allows easy single-hand access without interfering with weapon manipulation or sight picture. This is a practical capacity upgrade for tactical, home defense, and law enforcement applications where immediate access to spare rounds matters.

Constructed from 6061-T6 aluminum with a hard-anodized black finish for corrosion resistance. Installation requires partial disassembly of the receiver—the carrier mounts using existing trigger group pins and screws included in the kit. Basic mechanical aptitude and punches are needed; no permanent modifications to the shotgun. Shells load and eject positively with the spring-loaded retention tabs.
