I just picked up a Sightmark the other day, works great! I'm a bit concerned with the "Lock" hex bolt though, the included Allen wrench doesn't seem to fit it well; does your wrench lock into the hex bolt good & tight?Very nice. What kind of scope are you using on your 4095? I bought my wife a classic 995 and we took it to the range yesterday to sight in her new $29 sightmark reflex sight. She doesn't do very well with open sights but the reflex made a significant improvment. I couldn't help playing around hitting plastic bottles at 60 yards like it was nothing, and clays at 100 with a little more effort. These things are absolutely amazing. I actually did better with it than some folks were doing with their AR carbines.
