This MAAG is meant to be used with red dot sights. When using a red dot, it's super easy to shoot at targets. But pair it with a magnifier, and that target just got a whole lot easier to see. Using a magnifier with a red dot sight such as the X Site allows you to see a target much better. It adds magnification so you can view objects closer and clearer. The MG1 has the capability to fit on both weaver and picatinny style rails. Consequently, you can use the MG1 with any red dot sight. One of the best features of the MG1 is its flip-aside design. You can attach it to your gun, but if you don't want to use it, you can just flip it to the side instead of completely taking it off. If you do wish to take it off, however, this product has a quick-release feature that makes it easy to attach or detach from your gun.
