J&E Machine Tech 45-Degree Flip-Up Offset Sight Set, Aluminum

The J&E Machine Tech Flip-Up Front/Rear Sight Set (brand part no. TS-PS9B-AL) gives an AR-15 a folding backup sight option mounted at a 45-degree offset, so it disappears completely until needed. Machined from aluminum and finished in black, the set uses a slim, low-profile design paired with a quick-locking mechanism that snaps the sights into position when flipped up. The rear sight contains multiple-diameter apertures with windage adjustment, giving the shooter a choice of aperture for different lighting and range conditions and helping with quick target acquisition. At just 4.05 oz, the set adds very little weight to the rifle.
