Add a fast-transition backup sighting option to your rifle without giving up your primary optic. The Leapers, Inc. UTG Accu-Sync® AR15 45 Degree Offset Flip-up Front Sight (MT-745) is a rugged, low-profile offset front BUIS engineered for shooters who run magnified optics (LPVOs, prisms, scopes) and still want instant access to iron sights. With its 45° angled offset, manual flip-up design, and Posi-lock retention plunger, this front sight is built to deploy quickly, stay locked when in use, and hold zero on MIL-STD-1913 Picatinny rails.

If you’re searching for a UTG Accu-Sync 45 degree offset front sight, an AR15 flip-up front sight, or a Picatinny offset iron sight that pairs perfectly with a magnified setup, the MT-745 is a proven, practical upgrade.
45° Offset Design: Run Optics and Irons Together
The entire point of an offset sight is speed. The MT-745’s 45-degree angled offset lets you keep your main optic in place while giving you a rapid transition to iron sights—simply rotate the rifle slightly to bring the irons into view. This setup is ideal for close-range engagement drills, backup aiming, or any time your primary optic is obstructed or unsuitable for the shot. Leapers+1
Posi-lock Retention Plunger: Locked In When Deployed
A flip-up sight isn’t helpful if it can collapse or feel mushy under use. UTG’s Accu-Sync design uses a Posi-lock retention plunger to lock the sight securely in the deployed position, helping maintain consistent sight picture and confidence when you’re moving, training, or shooting under recoil.

Tool-free Front Sight Post Elevation Adjustment
Zeroing and fine-tuning shouldn’t require digging through a toolbox. The MT-745 includes a tool-free front sight post elevation adjustment wheel, letting you make elevation changes quickly and conveniently—great for dialing in at the range or making small corrections during training. Leapers+1
Built Tough: CNC Machined 6061-T6 Aluminum + Steel
This front sight is constructed from CNC machined 6061-T6 aluminum and steel and finished in matte black anodize for durability and a clean, non-reflective look that fits duty, training, and recreational builds. It’s designed to hold up to real use without adding unnecessary bulk to your rail. Leapers+1
Secure Picatinny Mount: Torx Screw + Squared Recoil Stops
Holding zero is the real test of any BUIS. The UTG Accu-Sync mounting system uses a single locking Torx screw and squared recoil stops to create a secure interface with Picatinny rails, supporting a strong zero hold and return to zero performance when installed correctly. Leapers+1
Correct AR-Height Geometry: Standard AR15 Center Height Above Rail
For compatibility and proper sight alignment, UTG lists a standard AR15 center height above rail of 1.42 in (36 mm)—helpful for planning your offset iron setup and matching it with the appropriate rear sight. Leapers
Pair It with the Matching Offset Rear Sight
To complete the system, UTG recommends pairing the MT-745 with the matching Accu-Sync 45 Degree Flip-up Rear Sight (MT-945) for a coordinated offset iron set. Leapers
