Pretty but dissapointing - TROY HK Folding Tritium BattleSight

Tried these on two rifles and had to raise the front post so high that the ring in ring sight picture had to be ignored. The front guard ring had to be held well below the rear peep ring which kind of defeats the purpose of the HK style ring in ring sight picture. Front sight was noticeably shorter than the matching rear peep sight when placed next to each other on the rail. Sent them to Troy Industries for manufacturer's warranty since I was beyond the 30 day return period and Troy treated me like I was stupid, offered no advise or alternatives, and sent them back to me, but admitted the detent rod was incorrect causing difficult adjustment and corrected it. For this price, these sights should have offered the flawless performance Troy claims, but that was not the case. I wanted to like these sights but would not recommend them to anyone. Be warned.
