The SureShell shotshell carriers provide reliable ammunition retention and are built to withstand the demands of daily use. Crafted from durable aircraft-grade 6061-T6 aluminum, these carriers feature an innovative rubber friction retention system and are designed to endure years of tough use. The yokes are precision-milled from 6061-T6 aircraft aluminum, then bead blasted and Mil-spec hard anodized for a rugged, non-glare finish. Featuring an integrated MIL-STD-1913 (NATO STANAG 4694) picatinny rail for optical sights, the SureShell carriers for the Benelli M2, M4 and M1014 models include mounting brackets with built-in top picatinny sight rails. These brackets securely attach using the top mounting screw holes, ensuring the shell carrier is firmly slung on the left side of the receiver for maximum security and a sleek, professional appearance. Proudly made in the USA, ensuring top-tier craftsmanship and quality
