## Description

desertcart.com : Monstrum Side Saddle 12 Gauge Shotgun Shell Holder | Compatible with Picatinny Mounting Platforms : Sports & Outdoors

Review: Shell Holder - Attached this to a pic rail I installed on a Benelli SuperNova. Shell holder is metal and seems quality made. It does take up some real estate. Make sure you have 12 sections on your picc rail for it to be installed. Holders have a nice snug hold onto the shells. Used some loc-tite on screws. See what happens when I take the gun out shooting. Looks nice.
Review: 5 star fit and function - This thing is durable. Installed in minutes. Made my shotg%n look badass. Function is great. Holds shells tight but not too tight. For the price you just can’t beat it.
