Bad turrets - Konus PRO M30 12.5-50x56mm Waterproof Rifle Scope

The Pro30 has a turret engineering defect. I have read several reviews that spoke negatively about the turrets. I too had problems. Both elevation and windage turrets were incredibly hard to pull out of the locked position. After about 20 time pulling up and pushing down both turrets loosened up. Next, I took the top screw out to check the turret zero. The windage turret was fine. The elevation turret wouldn't budge. I pulled really hard and the turret cap came off. It broke the rubber O-ring. The good thing is the elevation turret now works as intended. The bad thing is the turret is no longer sealed. The turret adjustment is very crisp. They are not as loud as clicks go. The glass is good. Very sharp at all powers. There is no haziness at the highest power. The parallax focuses well. I don't like the ocular bell adjustment. It has a locking ring. I prefer a non-locking ring setup. The reticle is good. The anti-cant bubble is a bit sensitive but a cool element. I won't send the scope to the manufacturer just yet. I'll wait until I go to the range and see if there are any other defects. That goes for a tracking test.
