Purchased an 2.5 MOA SRO on 5/9/23; SN 867##. Mounted it to a Glock 47 MOS. Dry fired probably a hounded rounds before heading to the range. Fired 100 rounds of 124 grain S&B to zero and begin vetting. Gun then got shelved for 4 months except for occasional dry fire while I focused on my DW’s.
Last week I took it out of the safe for more dry fire practice. The reticle shut off and would not come back on after just the 3rd dry fire. I loosened and then tightened down the battery cap but the reticle was still dead. I swapped out the battery and the reticle came back on for 5 or 6 dry fires before permanently dying again.
