## Overview

The UTG ACCU-SYNC Spring Loaded Flip-up Rear Sight is a precision-machined, aircraft aluminum rear sight designed for quick, tool-free windage adjustments and secure locking in both folded and deployed positions. Compatible with any Picatinny rail, it features squared recoil stops for reliable zero retention and pairs perfectly with the UTG ACCU-SYNC Front Sight, making it a durable, high-value upgrade for tactical and hunting rifles.

## Description

The UTG ACCU-SYNC Spring-loaded Flip-up Rear Sight features a tool free windage adjustment wheel, dual aiming apertures, and is precision machined from matte black anodized aircraft aluminum. Its low profile mounting base securely attaches to any Picatinny rail and uses squared recoil stops for a secure zero hold and return to zero. Our spring-loaded Posi-lock retention design locks the sight tower when it is both folded down and when it is automatically deployed, preventing the sight tower from collapsing when the sight is in use; designed to match our ACCU-SYNC Flip-up Front Sight, MNT-757.

Review: Good sights for a reasonable price. - Bought a front and rear for a “poverty pony build”. They work great and I got both for a fraction of the cost of some other brands. For the time being, these are my only sights on the rifle. At some point they will be my back up irons, but until then they are working just fine. They fit on my pic rail just fine. They are easy to adjust. They are metal. They have push button deployment and they lock in the up position. Yes, there are better options out there, but these are a very good value and are definitely serviceable sights.
Review: Tough sight, crisp adjustments. - For the money, this is a great sight. The latching mechanism is a little stiff at first, but add a couple drops of oil and it'll wear in nicely. The adjustment clicks and aperture detent are tight and positive. The stacked design saves rail space, but can leave you short on scope clearance with lo-profile rings. Compared to the MBUS, these are quite heavy as they are all metal. Also, unlike the MBUS, they do lock in the raised position, so they won't fold if you run into a solid object. These are so tough, however, any impact hard enough to damage the sights would probably total the gun as well. Overall, pretty happy with the UTG BUS.

### ⭐⭐⭐⭐⭐ It's a good site!
*by S***T on November 6, 2018*

Contrary to popular belief, UTG makes some damn good sites. I own multiple, and yes, they do primarily cater to the airsoft market, but their products are just as good on live firearms as well. Their 416 M4A1 site is probably one of my favorites! I have it mounted on an 6.8 SPC right now! It holds very well! I unfortunately, could use the 416 solid state site on my new AR, as it features a reflex site unlike my 6.8SPC, which uses a Vortex Strikefire 2, so I bought this site for my Core 15 M4 Tactical, and it works great! UTG sites - for the price, are built with solid quality. I've never once had issues with them loosing zero, I've never had issues with them falling off. They know what they're doing and that's how they dominate the market for those on a budget. Yes, I could've easily bought a Troy, I could've bought a Bravo Company, but the purpose of this site was to be a back-up, and that's exactly what this site fulfills. I zeroed it in 15 rounds, and can effectively engage targets out to 300 yards using a 25 yard zero using 5.56 NATO M855. .223 is a few click down in elevation, but can easily be compensated for with a few turns of the front site. The enthusiasts can say whatever they want, the fact remains, I get the same, if not better performance than they do on a $30 sight, then with their $100+ iron sites. I am very satisfied with my purchase. My only complaint about the product, but I don't see it worth knocking down a star, is if your rifle has the flat site that sites on top of your charging handle (like mine does) than your sites will be pushed forward to occupy 2 rail slots. I don't use magnifiers in this platform, so I'm not really worried about it (it's paired with a Sightmark Ulta Shot Plus) but it would be nice if this site was made to occupy only one rail slot and was able to occupy that space. Thanks UTG for making, what I perceive, as another great addition to my growing collection. Your sites have never once failed me.
