    Eotech has done it again by making the best even better in the EXPS3 series.

    There are 3 Reticle Choices available:

    • The classic 65MOA circle with 1 MOA aiming dot
    • 65MOA circle with (2) 1 MOA aiming dots, for basic .223 bullet drop compensation
    • 4-dot .223 Ballistic Reticle - calibrated for bullet drop of the M4 carbine at long ranges (designed to be ideally used with a magnifier)

    Offering true 2 eyes open shooting, a transversly mounted lithium 123 battery, and 7 mm raised base offering iron sight access, the new Extreme-XPS (EXPS) features easy to adjust side buttons and an adjustable, locking, quick detach lever for easy attachment and removal.

    Got the sight, put it on my rifle, attempted to begin to sight it in, but the up/down did not work at all. I sat there for probably 5 minutes turning it "down" and it didn't move at all. I even spent a good while turning it the other way just in case it was backwards and it still didn't move. Left/right worked just fine. But the sight is so high up you can barely see it while its on the rifle. It might be a good sight if it functioned, but you pay $600 for a sight, you kind of expect it to at least show up with knobs that work.

    Superior Optic

    I now own 4 of this model, 2 on M-4s and 2 on POF .308s. Super fast target acquisition with super fast follow-up shots. You get what you pay for and once you use it, you'll understand.

    great product

    Thanks for the great product. Going to order the G-33 later today.
