Keep every round type you might need — buckshot, slugs, less-lethal — organized, color-coded, and one grab away.

KEY FEATURES & BENEFITS

• CNC machined from 6061-T6 aluminum, hard-coat anodized matte black
• Rubber friction retention system holds shells firmly, up or down
• Replaces the factory picatinny rail using the same 5 drilled and tapped holes
• 100% made in the USA

PRODUCT DESCRIPTION

A shotgun's real advantage is flexibility of ammunition — but only if you can access the right load quickly. This side saddle organizes spare rounds against the receiver where they're visible, color-codeable, and instantly reachable, without any permanent modification to your M4.
