Dear Editor,
Blowing sand causes
smoking problems for the
M3A4 and M157. Sand blows
in the smoke discharge
holes± settles in the engine
chamber± and eventually
makes it difficult for the fog
oil to vaporize and produce
smoke.
We've sealed out sand with
barrel caps for the M²6 riFle.
Any time we're in a dusty,
sandy area, we put caps on
the three smoke discharge
hole spouts. The caps fit
tight after a ³Z-in long slit is
made on four points of the
cap. When it´s time to smokeµ
it's no problem pulling off
the caps.
Make slits LIke Th±s:
