A solid set of back up sights on your AR-15 platform rifle or shotgun is crucial, and the Troy Rear Battle Sight is a first-rate choice. When it comes to having an open sight on your weapon there are only two options. You either have them or eventually, you will wish you did. When you mount a Troy Industries Flip-Up Battle Rear Sight on your weapon, it's kind of the same as putting insurance on your car. You may never use it, but it's in place to bail you out if something goes wrong.
What makes this sight superior to others is the folding mechanism that allows the sight to lay flat when not in use. When you need it again, it can be flipped back into place while maintaining the zero perfectly! If you've never shot through a Troy Industries rear flip up sight, then you have no idea just how excellent they are. The Troy rear flip sight uses the traditional round aperture which has been proven in battle for nearly a century. While it may appear diminutive, the Troy Industries Flip-Up Battle Rear Sight locks in solid at the right height to provide a co-witness. Which works well if you run Red Dot or Holographic optics. Additionally, the Troy rear flip sight it isn't even ½ inch above the rail when folded. So, if you prefer a traditional scope, then the Troy Industries rear flip up sight is completely out of the way. The push-button locking mechanism ensures that they will not flip up or down unintentionally.
A zero-cant mounting system eliminates free play in the sight's position. Rugged construction of stainless steel and aircraft-grade aluminum allows the BattleSight to hold up under the most extreme conditions. The Troy rear sight attaches to your Picatinny rail literally in seconds and stays put until you decide to move it. Also, you can change the aperture size on your Troy rear sight with the flick of your finger and that locks solidly as well. You can choose a large aperture for up-close and personal work, or a small one so you can reach out and touch someone.
