Product Description

Our New Spigot system for the AI Chassis is here!

We spent a lot of time perfecting what we feel is the best rail system currently in production for the AI Chassis. It is produced from the finest steel and aluminum that we could get our hands on. We then coated it with the best Mil-Spec coatings out there. Our spigot attachment is pre heat treated, turned, ground and polished steel. The spigot attachment is then final machined on a CNC Lathe. The Rail is 7075-T6 aluminum which is considerably tougher than 6061. Most other companies produce their rail systems out of 6061, because it is considerably cheaper and easier to machine, but it is also completely inferior to 7075-T6. Our Rails are finished on top notch CNC mills and meet the original Picatinny rail specifications, alternatively known as the MIL-STD-1913. When finished the aluminum parts are mil-spec annodized and the steel parts are mil-spec black oxide coated.

These rails lock up like vaults when tightened to the chassis.

Please check out the Harris Bi-Pod Adapters for our rails. We also offer AICS cheek piece Thumbscrews.
