Description

The UTG ACCU-SYNC front sight is one of those parts that punches well above its class. It's a spring-loaded flip-up that deploys the instant you hit the Posi-lock push button, popping the sight tower straight up and holding it there. When you fold it back down, it locks flat and out of your line of sight, so it stays put whether you're running an optic over the top or just keeping it stowed until you need it.

The body is machined from aircraft aluminum with a matte black anodized finish, and the important hardware inside is steel, including a standard A2 front sight post. That A2 post is the same one found across the AR-15 world, so it's easy to swap for any aftermarket post with matching dimensions if you want a thinner or taller blade. Elevation adjusts through the post the same way a traditional A2 sight does, which keeps things familiar for anyone who has zeroed irons before.

What Makes the ACCU-SYNC Hold Its Zero

A lot of budget flip-ups loosen up under recoil, and UTG went after that problem directly. The low-profile base clamps to any MIL-STD-1913 Picatinny rail using a single locking Torx screw, and there are square-shaped integral recoil stops built into the base. Those stops take the beating instead of the screw, so the sight returns to zero after you pull it off and reinstall it. UTG lists a recommended torque of 35 in-lbs on the locking plate, which is worth following for a rock-solid mount.

Pairing Up the ACCU-SYNC Front Sight

This front sight is built to match the UTG ACCU-SYNC flip-up rear sight (MNT-957), and the two sit on the same level plane whether you mount them directly on a handguard or on a high-profile gas block rail. Run them as a complete backup set behind a red dot or magnified optic, or use them as your primary irons on a lightweight build. At right around an ounce, it isn't adding any real weight to the front of your rifle, and it's backed by UTG's lifetime warranty.

Frequently Asked Questions

Does the ACCU-SYNC front sight use a standard A2 post?

Yes. It uses a standard A2 front sight post, the same style found across AR-15 rifles. That means you can swap in any aftermarket post with equivalent dimensions if you prefer a different blade width, and you adjust elevation through the post just like a traditional A2 sight.

Will this flip-up front sight hold zero under recoil?

It's designed to. The base uses square-shaped integral recoil stops that absorb the shock so stress stays off the single locking Torx screw. UTG recommends torquing the locking plate to 35 in-lbs, and with that done it returns to zero reliably even after being removed and reinstalled.

Can I pair the ACCU-SYNC front sight with a matching rear?

Absolutely. It's built to match the UTG ACCU-SYNC flip-up rear sight (MNT-957), and the pair sits on the same level plane. You can run them as a complete backup iron set behind an optic or as your primary sights on a lighter build.

How does the sight deploy and fold down?

It's spring-loaded with Posi-lock push button activation. Press the button and the sight tower springs straight up and locks in place so it won't collapse while you're aiming. To stow it, just fold it back down where it locks flat and low-profile out of your sight line.
