Griffin Maritime Receiver Extension (AR15 & AR10 Options)

Griffin Armament 7075-T6 Maritime Receiver Extension. A six position, mil-spec dimensioned receiver extension featuring 7 ports to allow excess gas, water, oil, and debris to leave the operating system, reducing pressure and associated danger to both host firearm and shooter, while enhancing reliability. Mil-spec hardcoat anodized. 7075-T6 is twice as strong as 6061-T6. Don't put a weak 6061 receiver extension of dubious origin in your defensive firearm. The life you save might be your own.

The longer pictured Maritime Receiver Extension is for use with AR10 systems. The shorter pictured Maritime Receiver Extension is for use with AR15 style systems.
