Description
Superlative Arms (SABO) AR-15 piston drop-in retrofit kit. Converts a direct impingement AR-15 to a piston-driven operating system, or serves as the core of a new piston build.
Why piston?
Piston systems run cooler, leave less carbon in the receiver, and reduce gas blowback when you run a suppressor. The operating rod cycles the action in place of a gas tube.
What is included
- .750″ solid piston gas block with set screw mount, right hand
- Forward-facing adjustment controls, with the exterior locking detent
- Dark DLC-coated carrier, mid length
