Adding optics to your weapon should be straightforward, right? All you want to do is clamp this new T1 onto your Picatinny rail and get to shooting. That is a simple enough task until you add open sights to the picture. Do you need to go with absolute co-witness, lower 1/3 co-witness? What if you have more than one gun, and you want to share this shiny new glass with yourself? Strike Industries has the answer.

Can I Get A Witness?

Choosing the correct height AR Optic Mount will either make your day or break it. First, the option of having mechanical backup sights is a no-brainer. I believe that having options is as well. Keep in mind that the gun you're setting up right now might be your first, but it probably won't be your last. In life, everything changes, and that includes what you like. The Strike Industries REX T1 Riser Mount comes with the spacer you need for those options. You get either absolute or lower 1/3 co-witness out of only one purchase. Now switching the height of your T1 compatible optics doesn't mean buying another part.

Don't Strikeout

You can find an AR optic mount that comes in at all different shapes and prices. Some are made to look pretty, and some are plain junk. However, the Strike Industries REX T1 Riser Mount is made by shooting experts for real shooters. Strike works through design with its R&D engineers. They then take it to the range and hammer out the unseen functionality issues before going into production. Therefore, you get a quality AR Optic Mount that lives up to its name. Their customer service, price-point, and guarantee is top-of-the-line. It's time to Strike.
