Built for durability, SureShell shotshell carriers securely hold ammunition and withstand the rigors of daily use. Machined from 6061-T6 aircraft aluminum, the carrier yokes feature an innovative rubber friction retention system and a tough construction designed for years of reliable service. The yokes are bead blasted and Mil-spec hard anodized for a rugged, non-glare finish. An integrated MIL-STD-1913 (NATO STANAG 4694) Picatinny rail allows for the mounting of optical sights.
