So I have a TA-31 with green horsehoe, practically brand new condition, tritium bright as the sun, but the windage line on the right side is very faint whereas the left side is dark and crisp
Any ideas?

Direct from Trijicons FAQ on their website.
The right hand side of the crosshair is blurry. Is this normal?
Yes. The reticle pattern in the ACOG is formed by removing highly reflective metal from a prism mirror. This mirror is at about a 45-degree angle inside the gun sight. This means that the left side of the reticle is closer to the eye than the center of the reticle and the right side of the reticle is further from the eye. The result- the right side of the reticle is focused beyond infinity which can cause distortion on the right side of the reticle. The perceived distortion will be more or less depending on an individual's eyesight. The left side of the reticle is unaffected because the human eye has no difficulty focusing on a closer object. This in no way detracts from the performance of the scope. The image of the target area is not affected. Only the right hand side horizontal reticle line is blurry. This construction is required to achieve a parallax free vertical center of the scope, which allows the built in ranging on the reticle pattern. |

I thought it was ranging for artillery. |

The only explanation I've ever read is that the hashes are (very mildly) useful for calling out location to teammates. As in 'two hashes to the right of the tree' or some shit. I've never seen them used ever, and as far as I am concerned they're mostly there for looks. Blurry looks. |
