JE Machine Tech TS-PS9B Features The Je Machine Tech Flip-Up Front and Rear Sight Set mounts at a 45-degree offset on a Picatinny rail positioning the sights so they stay clear of a top-mounted optic until the shooter rotates the rifle to bring them into view. This offset arrangement gives a shooter a fast backup sighting option in the event of an optic failure or depleted battery without requiring the primary optic to be removed. A quick locking mechanism holds each sight securely in the flipped-up position supporting rapid target acquisition when the rifle is rolled to the offset angle. The rear sight includes multiple diameter apertures letting the shooter choose between a wider aperture for close fast engagements and a tighter one for more precise aiming at distance. Both sights are built from glass filled polymer a lightweight yet durable material that keeps the overall weight of the set to just 0.20 lb while still standing up to the recoil and handling of regular range use. The rear sight includes windage adjustment alongside the elevation capability on the front post allowing the shooter to zero the backup sights independently of the primary optic. Measuring 2.15 long 1.75 tall and 4.05 wide as a mounted pair the low profile design keeps the rifle s silhouette slim when the sights are folded down. Finished in black to match typical AR builds this sight set gives any optics-equipped rifle a dependable mechanical backup.
