2. No maintenance is needed on the sight’s surface, except to occasionally wipe off with a soft
cloth. Use only a water-based cleaner such as glass cleaner, ammonia, or soap and water.
Never use any solvent-type cleaner such as alcohol or acetone. Do not use gun cleaner to
clean or lubricate the HWS.
3. All moving parts of the sight are permanently lubricated with the exception of the quick
release lever. If audible sounds are generated when opening/closing lever, add a drop of
lubricant to lever assembly. Do not try to lubricate any other moving part.
4. Never disassemble the sight’s optical assembly! The optical cavity is purged, nitrogen filled,

damage the sight.
