This option is for our customers that want a stricter spot spec offered from the factory. This option is hand selected strictly to meet the above aviation spot spec. Even though PVS-31a’s in general have incredible tubes, spots are still a reality in all night vision. If you are a customer that wants to insure a stricter spot spec this is a great option. Please understand that although an aviation spot spec is way stricter than the milspec spot spec, spots </= .003″ are still acceptable and are a reality of night vision.
Includes a Improved Counterweight Kit, put your color option on the order notes (MC, Black MC, or Coyote)
Please allow for additional lead time for aviation grade as this is a stricter spot spec than offered from L3Harris. Since we cannot order these to an aviation spot spec from L3Harris we cannot quote a definitive lead time. On average this option takes 60-90 days longer than the standard option.
