Griffin Armament has recently announced two maritime receiver extensions optics for the AR-15 and AR-10 patterns.
Griffin Armament states “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.”
