King Arms 7" RAS Receiver Assembly - VIS

Constructed with Aluminum, the King Arms VIS combines the receiver and the RAS hand guard into a single piece, thus providing increased strength, durability, and accuracy; it is a very robust design. It features 20mm Picatinny straight rail systems, very realistic VLT markings and a unique serial number laser etched into the body.

Additional features present in the King Arms VIS Receiver Assembly are: # A self-locking front pivot pin and takedown pin.


The pins stay safely on your lower receiver as you quick detach your upper receiver in 2 seconds!

A redesigned bolt catch system, which will be installed inside the metal body.


The bolt carrier ornament plate can be held in the open position when you pull back the charging handle. But as soon as you release the bolt catch, the ornament plate will quickly slide back to its original closed position!
