The SureShell carrier system for the Kel-Tec KSG upgrades the shotgun with a replacement anodized aluminum Picatinny optics rail. This rail supports one or two aluminum and/or polymer shell carrier yokes, each holding six shells. Small aluminum flanges on the rail's sides allow for the addition of short Picatinny rail sections (a 2" section is included) for attaching accessories like lights or lasers. The rail assembly is securely mounted using two unique steel recoil blocks with angled set screws. The SureShell aluminum shotshell carriers, integrated with the rail, are machined from aluminum and employ Mesa Tactical's rubber friction retention system. This system ensures shells are held firmly and reliably, even under heavy recoil, providing a robust and secure mounting solution for the loaded carrier.
