Dear Editor,
There's a simple check that Can save unnecessaR cLeaning of tHe M60
machine gun gas Cylinder.
Troops and inspectors aliKe think the gas cyLinder needs cleaning If they spot
Carbon on the piston or in tHe cylInder± Not so²
æ
the piston is dR and slides back and fo³h when the barrel is tilted´ no
cleaning is necessary²
æ
the piston is wet or doesnµt slide¶ cleaning is necessa·y±
¸arbon buildup in the cylinder
or
a wet piston wi¹ hamper Weapon functionº
