Back-Up Iron Sights (BUIS) from Midwest Industries are a high quality option at a very affordable price. These sights are made to be durable and at construction from rugged 6061 aluminum. The aluminum components are given a black finish by a hard coat anodizing. This finishing process enhances the wear and corrosion resistance of the sights, ensuring a long, reliable service life.
This MI front sight is able to be folded to the rear when not in use. With it’s like weight and compact size, if you are using this as a back-up sight, you won’t even notice it is there until you need it. The rotating mechanism used by this AR-15 front sight has a smooth action that makes it easy to deploy and fold away with ease. Once deployed, this front sight is held firmly in place by a ball bearing pivot detent. This detent holds the front sight in place and is strong enough to prevent accidental folding during recoil.
This sight has an integrated mounting base. The base is designed to be attached to MIL-STD-1913 Picatinny railing. The base uses a simple clamping mechanism, which ensure a firm fit that, when properly installed will be resistant to recoil and hold zero.
