One of the many advantages to the AR-15 platform is its compatibility with a range of optics options, thanks to an industry-standard Picatinny optics rail that runs along the flattop upper receivers seen on most modern-day guns. However, electronic optics can lose battery power and magnified optics can be cumbersome for some close-range applications. Enter the UTG ACCU-SYNC flip-up sights from Leapers.
Optimized for use with the AR platform, the ACCU-SYNC design features a height over the bore that's designed to accommodate firearms with stock combs in line with the rifle's barrel. The front and rear sights are equipped with the company's Posi-Lock system, which provides a spring-loaded folding mechanism. When other optics are in use on the rifle, simply fold the front and rear sight down along the top of the Picatinny rail for an unimpeded sight picture. When the back-up irons are needed, depress the Posi-Lock button, and the sights spring up and lock into place.
On the UTG ACCU-SYNC rear sight, windage is adjustable through the inclusion of a toolless adjustment wheel. A dual-aperture design provides a small and large peep sight, and users can quickly swap aperture sizes, depending on whether they're engaging at close or extended distances. At the front, the ACCU-SYNC system uses a standard A2 front-sight post, which is adjustable for elevation using standard tools. Consumers can also swap the post for all A2-style aftermarket sight posts.
Both the front and rear sight attach to all Picatinny top rails with a single Torx screw that clamps down on a side plate and secures recoil stops located on the bottom side of the sight. Each sight is machined from aluminum and is treated with a matte-black finish. The UTG ACCU-SYNC front and rear sight, individually, retail at a suggested price of $32.97.
