Do not depend on the fact that no chambered round was ejected on clearing. You can still have
a live round in the chamber that did not extract/eject because your extractor was broken, or the
case rim was ripped off by the extractor. VISUALLY inspect the chamber to ensure it is clear.
1.6 Characteristics of the M6 Series of Rifles
e M6 is an Incrementally Evolved version of the proven M4 carbine. It is a lightweight
short stroke gas piston operated, air cooled, magazine fed, semi-automatic carbine (select fire
available to Law Enforcement and Military). e weapon operated by a proprietary Short
Stroke, Self-Regulating, Gas Piston Operating System. Unlike traditional direct impingement
gas operating systems the gas piston system in your rifle harnesses the energy of gasses tapped
from the barrel to operate the weapon. e M6 does not vent hot, carbon laden gasses into the
action of the rifle or the rifle’s upper receiver. Once sufficient energy is produced to cycle the
weapon all excess gasses are vented below the rail system or hand guards harmlessly. e kinetic
energy is transferred from the piston cup to the intermediate rod and operating rod to the bolt
carrier key. is will save you many hours of maintenance as the system is inherently clean. You
will find the system requires less lubrication as the lubrication does not burn off.
