Strike Industries SPBUS Strike Polymer Backup Sights Black Folding for AR15 - SPBUS

The Strike Polymer Backup Sights SPBUS is a lowprofile affordable sighting system that is designed for the AR platform and has bonus builtin sights when flipped down. No time to flip up the sights you have backup sights on your backup sights. The SPBUS sights are made with lightweight and durable SI Polymer Extreme material with steel mounting tab and insert that can handle any wear and tear you throw at it without any major issues. As long as youve got a Picatinny rail you will have these SPBUS mounted in minutes. Both sights are capable of flipping down nice and low so you dont have to worry about them being in your way when theyre not in use or snag on any gear. The SPBUS does not have an internal spring so you dont accidently deploy the sights when you dont need them. Since the SPBUS sights are slightly taller than standard A2 sights 2.3mm0.09 taller the SPBUS is designed and optimized to have both sights paired together and not with other sights. To zero the sights or make any adjustments the rear sight has an easytouse knob for adjusting windage while the front sight elevation is easily and quickly adjusted without tools. The rear SPBUS has dual apertures at 4.70mm0.19 for longer eye relief low light and faster target acquisition and 1.75mm0.07 for shorter eye relief and greater accuracy. Quickly slide the rear sight up and down to change to the aperture you need.
