UTG AR15 Super Slim Fixed Rear Sight, Picatinny

• Super slim fixed profile: The low-bulk rear sight keeps the rifle streamlined while remaining constantly ready, making it a practical choice for backup sighting systems and rifles that stay configured for immediate use.
• A2 dual-aperture rear sight: The dual-aperture layout gives the shooter a fast option for closer work and a more precise aperture for deliberate aiming, so the sight adapts well to mixed distances.
• Tool-free windage and elevation adjustment: On-rifle adjustments are straightforward in the field, allowing quick zeroing or correction without carrying extra tools for the sight settings themselves.
• 6061-T6 aluminum base with steel sight assembly: This combination keeps weight manageable while placing steel where repeated adjustment and sight use demand durability.
• Picatinny clamp with integral recoil stop: The single locking screw and squared recoil stop help the sight stay secure on a MIL-STD-1913 rail and support consistent return to zero after removal and reinstallation.

About the UTG Mounts Series

UTG Mounts covers Leapers' broad range of mounting solutions and related hardware for modern sporting rifles, hunting optics, and general shooting applications. Within the wider UTG lineup, the series is aimed at shooters who want practical, robust interface components that match common platforms and sighting systems without unnecessary bulk. The family includes products built around Picatinny compatibility, with variants across rings, cantilever mounts, and other rail-mounted accessories for different optic tube sizes and rifle setups.

The design approach behind the series focuses on secure attachment, repeatable alignment, and compact form. Across the range, UTG emphasizes straightforward installation, recoil control through positive engagement features, and profiles that work well on AR-pattern rifles where rail space is shared with optics, iron sights, and accessories. In practical terms, that means mounts and sight bases that are intended to hold zero reliably, fit cleanly on standardized rails, and remain easy to integrate into both simple and more specialized rifle builds. For shooters assembling a dependable carbine or refining a practical range setup, UTG Mounts is positioned as a functional, system-oriented part of the rifle rather than an afterthought.

About the UTG AR15 Super Slim Fixed Rear Sight, Picatinny

The UTG AR15 Super Slim Fixed Rear Sight, Picatinny is a fixed rear iron sight built for AR-platform rifles that need a constant-ready aiming solution without the bulk of a traditional carry-handle assembly. Its super slim profile helps preserve rail space and keeps the rifle easier to handle around optics, magnifiers, or other top-rail accessories, while the fixed format eliminates the extra step of deploying a folding sight before use.

The sight uses an A2 dual-aperture rear assembly with a 6/3 drum, giving the shooter a familiar AR-style sight picture with two aperture options for different shooting conditions. That makes it suitable for rifles used across general range work, training, and practical carbine setups where a larger aperture can support faster target acquisition and a smaller one can help with more deliberate aiming. Tool-free windage and elevation adjustment further supports this role by allowing zero changes and corrections to be made directly on the rifle.

Construction combines a precision CNC-machined 6061-T6 aluminum base with a steel A2 sight assembly, balancing weight and durability in the areas that see the most handling and adjustment. The sight mounts to a Picatinny rail using a single locking Torx screw and an integral squared recoil stop, a layout intended to keep the unit firmly seated under recoil and maintain zero consistency. At 3.5 oz (99 g) and 2.4 in (60.93 mm) long, it remains compact enough for streamlined AR builds while still providing standard AR15 center height over rail.

About UTG

UTG is the product brand of Leapers, Inc., a company founded in Michigan in 1992 and headquartered in Livonia, Michigan, United States. Leapers began with a compact 4x28 scope and expanded into a broad catalog of shooting accessories and optics, including riflescopes, mounts, rings, and bipods. The company is closely associated with practical equipment for hunting and shooting sports, with a strong focus on the interface between firearm and optic.

That background is especially relevant in categories such as rails, mounts, and iron sights, where repeatable fit and durable construction matter as much as the sighting component itself. Leapers later expanded its manufacturing and development capabilities, including the introduction of the UTG PRO line in 2009 and the establishment of an optics research and manufacturing center in Taiwan in 2018. In the market, UTG is known for producing functional rifle accessories that emphasize compatibility, straightforward installation, and practical field use.
