Disappointment and regret - Sightmark Ultra Shot QD Reflex Sight

Mounted on Ruger Target 10/22 20" bull barrel to replace bulky target scope.

Changing carbine configuration to use in Steel Challenge 20-75' range

At 25 yards, bench rested, first unit would not zero on 3 reticles, but came "close enough" to use on steel.

4th reticle would move POI 6" right & 4" down...or 5" right & 2" down....or 7" right & 3 inches up.....Returned for refund.

Dealer gave no hassle replacement of same model and BORE SIGHTED.

1st Range trip with new unit took 200 rounds to get within 2" of POA....at 25 FEET bench rested!

THIS is on a 10/22 that was regularly grouping 25 shots into under 1" at 50 yards when using a 6-24x44 target scope, now unable to even get IN a 2" bulls eye at 25 feet! All four reticles did give similar groups, which I was willing to try on the Steel Match as targets are 6-12" at close range and only need to ding the target.

2nd range trip found dead battery.
3rd range trip with new battery, checked out before leaving to go to range, great reticle illumination. Got to range...NO sight picture. Fiddled with it for 30 minutes....changed battery 3 times, no help. Dead.

Got home, checked sight....NOW there's a fine reticle image!

Will try ONE more time for critical evaluation.

So far, not happy.
Pros: price; size; configuration; reticle choices
Cons: wandering zero
