Very Disappointed

by Mark, Verified Owner from VA, United States Written on March 21, 2021
Bought the MK4 to work with DBAL-A3. Received light and construction appeared to be of high quality, what i would expect from Steiner. Tested light with push button and it operated correctly. Attached to weapon and connected remote switch from A3. Tested good. Placed weapon in safe. Pull weapon out 3 weeks later to do low light drills and it light failed to function. Replaced batteries and still failed to operate. Very disappointed. Contacting Steiner to correct.
Pros:
  • None at the moment, failed to function when needed
Cons:
  • Did not work when need
Would recommend: No
