TacFire AR-15 45 Degree Low Profile Pop Up Sights Features The TacFire AR-15 45 Degree Low Profile Pop Up Sights are molded from polymer for a combination of durability and light weight that keeps them from adding unnecessary bulk to the rifle. The front sight uses an adjustable A2 post paired with a ball bearing pivot detent and posi-lock design which snaps the sight into place and holds a consistent zero every time it is deployed. This same-plane design keeps the front and rear sights aligned with each other for a predictable sight picture. The 45 degree mount angles the sights off the top rail keeping them out of the way of a primary optic while remaining instantly accessible. The rear sight offers windage adjustment along with two selectable apertures giving the shooter flexibility between a wider aperture for fast close range target acquisition and a smaller one for more precise aim at distance. Mounted at a 45 degree offset both sights fold down flush when not in use and pop up quickly when needed without interfering with a magnified optic or red dot sitting on the main rail. Finished in OD Green these sights suit rifles built around a tactical or outdoor color scheme. The TacFire AR-15 45 Degree Low Profile Pop Up Sights are a practical affordable backup sighting solution for any AR-15 platform rifle.
