UTG ACCU-SYNC Spring-Loaded AR15 Flip-Up Rear Sight - Matte Black

The UTG ACCU-SYNC Spring-Loaded AR15 Flip-Up Rear Sight is a no-frills backup optic solution built for shooters who want their iron sights ready when they need them. Machined from aircraft aluminum and finished in matte black, this flip-up rear sight uses a spring-loaded mechanism that deploys quickly and locks securely in place, so your sight stays up when you're running it—no wobble, no surprises downrange. Whether you're running a primary optic setup and want reliable irons in reserve, or you prefer a full iron configuration, this sight gives you the rugged simplicity that flat-top AR platforms demand.

The Posi-lock push-button activation is the real workhorse here. Press it, the sight tower springs up and locks, and it stays locked. Drop it back down when you don't need it. No springs to fatigue, no springs to fail—just solid engineering. The matte black finish won't catch light and plays well with modern tactical setups and hunting rifles alike. At this price point and with this robust construction, it's the kind of accessory that earns its spot in the truck or the safe.

If you're building or upgrading an AR, whether for home defense, sport shooting, hunting, or training, having a quality backup sight is never wasted money. The UTG ACCU-SYNC delivers on the fundamentals: it's built to last, it does one job extremely well, and it won't let you down when you need it.
