If you’re searching for a UTG flip-up rear sight, a low profile Picatinny rear sight, or the exact MNT-955 dual aperture rear sight, this is the right model for building a modern, optic-friendly rifle that still has dependable irons when you need them.
Flip-Up Rear Sight: Essential Backup for Optic-Equipped Rifles
Modern rifles often run red dots, prisms, and magnified optics—but optics can fail from impact, dead batteries, or environmental issues. A flip-up rear sight provides a proven backup aiming solution that can keep your rifle functional even if your primary optic is compromised.
A folding rear sight is ideal for:
AR-15 and AR-style carbines with red dots or LPVOs
Training rifles where irons are required for drills or qualification
Backup sight systems designed for redundancy and reliability
Rifles kept for practical readiness and everyday range use
Because it folds down when not in use, it won’t clutter your optic view or take up unnecessary space on the rail.
Low Profile Design: Clean Rail Setup and Optic Compatibility
This UTG rear sight is built with a low-profile design, meaning it sits compactly on your rail and folds down neatly when not deployed. That low profile helps you:
Maintain a cleaner top rail for optics and accessories
Reduce snag points during transport and handling
Improve compatibility with a variety of optic setups
Keep your rifle streamlined and modern in appearance
For shooters who prefer minimal bulk on the receiver rail, a low-profile flip-up sight is the ideal style of backup iron.
Fits Picatinny Rails for Wide Platform Compatibility
The MNT-955 is designed to fit Picatinny rails—one of the most common mounting standards across AR platforms and many other tactical and sporting rifles. Picatinny compatibility makes it easy to install and reposition as needed for your setup.
It’s a great fit for:
AR-15 / AR-platform rifles with Picatinny top rails
Tactical carbines and training rifles
Rifles with rail sections designed for rear iron sights
Any compatible firearm platform using a Picatinny mounting interface
Dual Aiming Aperture: Versatility for Different Conditions
One standout feature is the dual aiming aperture, which gives you two sight picture options—typically useful for switching between more precise aiming and faster acquisition depending on your needs.
Dual aperture benefits commonly include:
A more precise option for controlled, deliberate shooting
A faster option for closer-range or quicker target transitions
Better adaptability across different lighting environments
Practical flexibility without changing equipment
For shooters who want a rear sight that can adapt to different distances and use cases, dual aperture functionality adds real value.
Black Finish: Professional, Low-Glare, and Easy to Match
The black finish pairs naturally with most receivers, handguards, optics, and other accessories. It’s ideal for:
All-black AR builds
Two-tone rifles where black accessories provide contrast
Low-glare setups for practical range and field use
Matching a UTG flip-up front sight for a consistent set
A clean black finish keeps your sight system looking cohesive and purpose-built.
Ideal for Backup Iron Sight Sets and Training Rifles
This UTG flip-up rear sight is an excellent choice for:
Completing a flip-up iron sight set (paired with a front flip-up sight)
Co-witness-capable setups (depending on optic height and configuration)
Training rifles where iron sight drills are part of the program
Rifles that need a dependable backup aiming option without extra bulk
If you want a practical, affordable rear sight that integrates cleanly into a modern rifle build, the MNT-955 is a strong option.
