Tritium not visible. - TROY HK Folding Tritium BattleSight

It’s a Troy folding front sight. There’s not much to say that’s not been said in the other reviews. Troy works well and is battle tested.
I have the fixed front HK style sight on my iron sights only rifle and I thought I’d try the Tritium option.
I’m replacing it with a standard front sight post when the time comes. The Tritium was just not visible to my eyes. I focus on the target for close and moving shots and on the front sight post for medium range shots. It just doesn’t stand out. Other reviews warned about the same and that’s my excuse. I had to not see it for myself. It’s not worth returning as I’d only replace it with the standard folding hk style front sight and the difference is only $13.00 for the standard folding front sight. The post loses some adjustment value as it has to spin 360 degrees. 180 degrees since it’s not visible (hahaha). I thought I could stack the dots with my 2 moa RDO but it just didn’t pan out. Dope idea? Lol. Pew Pun intended.
