As mentioned above, the Triji glass is really nice. But, the unfortunate thing for the 5-20x with the mil reticle (which looks like the TR23G model is the triangle) is that it is paired with moa adjustments. My current favorite AR scope is the 1-4x24 with amber triangle, but for long range it certainly isn't ideal. You can dial elevation easy in moa, but you have no reference points to hold for wind, so you'd be dialing it too.
I wish there was a FFP 5-20x50 with a little thinner mil dot reticle with mil adjustments. They'd sell the snot out of em.
