Look for Problems
Make sure the rear sight’s ears aren’t so bent
that the sight can’t be raised. Check that the
block for the rear sight’s windage scale isn’t
loose. If it is, the scale won’t stay in position.
Feel the charging handle for looseness. If
it gets too loose, it can come off completely
during ±ring. Your repairman can quickly
tighten the handle with a
3

4

feel the charging handle’s slide plate for
looseness. If it has any play, it could cause
charging problems.
