    Great design. Does what it’s supposed to. Protects. Looks good. Saved me 800 from buying a t-2 cause it looks similar now. Id recommend and buy again.

    On Primary Arms advanced red dot

    This is a great cover that I put on a P.A. advanced red dot. Not a perfect fit of course but it wasn't designed for the P.A. It fits great and protects the red dot. The f.d.e. is lighter than Magpul's but darker than BCM's. As others have said it slides on easier if you warm up the cover with a hair dryer.

    My first time using TD iO cover. Very nice material, easy to take on when you do it right. Does a good job protecting and shield the lenses for water and dust without loosing the cover.

    Keeps on getting better....

    Posted by Unknown on 14th Jan 2018

    I purchased one of the first generation of this product when I bought my T-1 because I couldn't stand the bikini lens covers that came with it. It was such a simple design and did exactly what I wanted. Now, TangoDown is on it's third generation and appears to fit even better on the optic. Everything feels like it's more heavy duty and the FDE color looks great on my rifle.

    If you run a T-1, get this. Period. Keeps the optic dust free and covered when not in use. And the caps themselves snap together to perfectly move out of the non dominant eyes' sight line. Easy to snap and unsnap but not too easy.

    Tango Down IO

    Posted by matt c on 21st Dec 2015

    Must have for the Aimpoint T1 for two reasons. 1. The stock Aimpoint rubber caps are really soft and will conform to the outer diameter of the lenses leaving a semi-permanent cloud on the lense. 2. It allows for 1 handed manipulation and keeps it in a nice tight, small, and clean package. Wish I would have purchased them before my lense got scuffed up.
