That rear sight is a little unusual to look through. Its hardly comfortable. Do what feels right. Recheck your point of impact after you move them. I wouldn't use them for accuracy in the first place. Only for back up or pest control without an optic. Though I have heard the farther apart the two sights are the more it helps accuracy. I think ill give it a try anyway. Im curious.
I peeked at the troys online the other day. Its a toss between them and the diamond head. Diamondhead has an auto ranger front sight which is pretty nice. Troy sights just look indestructable. The flip up ones that are on the m4 were nice. I kind of like them. Try were pricey though I think I remember they were steep. I just want easy elevation adjustments in a flip up sight. But zeroing for 300 and aiming lower is easy enough. Trots seem like the caddys of battle sights.
