SureShell shotshell carriers for the Beretta 1301 feature mounting brackets with integral top Picatinny sight rails. Using the top mounting screw holes found on the Beretta 1301 shotguns, the SureShell shotshell carriers are thus slung on the left side of the receiver, securely fastened at the top. No other shell carrier mounting method is as secure or looks as good. The Picatinny rails are machined from aircraft grade 6061-T6 aluminum, which are mil-spec hard anodized and provide an extremely durable non-glare matte finish. The basic saddle rail design provides a robust mounting platform suitable for mounting a variety of optical sights, while a second version, which is nearly identical to the basic version, also includes a Mesa Tactical four, six, or eight shell SureShell shotshell carrier mounted on the left side of the receiver. Both versions are manufactured in compliance with MIL-STD-1913 Picatinny specifications, and no gunsmithing is required for installation.
