Overview of the MBUS 3 Sight Set
MBUS 3 – The Next Evolution

Key Differences from MBUS and MBUS Pro
- Thinner profile
- Lower snag risk
- Enhanced compatibility with modern optics
MBUS Pro uses metal, but MBUS 3 gives you lightweight durability at a fraction of the cost.
Designed for Picatinny Rails
No special tools, no nonsense. Just snap these onto your Picatinny rail, tighten them up, and you’re ready to go.
Build Quality and Materials
High-Strength Polymer Construction
Don’t mistake “polymer” for “flimsy.” These are impact-resistant and have gone through serious abuse testing. Think of it like the Glock of BUIS—tough, dependable, and built to last.
Compact, Lightweight, and Rugged
With both sights weighing in at just over 1 oz each, they won’t weigh down your build. Whether you’re running a featherweight PCC or a 16” duty AR, these keep things nimble.
Compatibility with Picatinny Rails
Universal Mounting System
If your rifle has a Picatinny rail, you’re golden. The MBUS 3 was made to drop in with zero compatibility drama.
Ideal Use Cases – AR15s, PCCs, Shotguns
Whether it’s a defensive build, competition carbine, or just a range toy, this sight set fits in perfectly. Even pump-action shotguns with a rail can benefit.

Sight Performance in the Field
Spring-Loaded Flip-Up Mechanism
Push a button, and bam—your sights are up. No fumbling. No sluggish deployment.
Positive Locking System
Once deployed, they stay put. No accidental flops or wobbles—these things lock tight like a vault.
Windage & Elevation Adjustments
- Rear sight: Dial windage with precision
- Front sight: Elevation changes are smooth and tool-free
Front Sight Features
Narrow Profile for Better Optic Compatibility
Running a magnifier or large red dot? The MBUS 3’s narrow profile plays nice. No interference, no headache.
Tool-Free Elevation Adjustment
No need to pack a flathead screwdriver or sight tool. Just twist and go.
Rear Sight Features
Dual Aperture Options
Switch between:
- Large aperture for close quarters
- Small aperture for precision at distance
It’s like having two sights in one—because you kinda do.
Precise Windage Dial
Click-adjustable, tactile, and intuitive. You’ll zero in fast without the guesswork.
Ease of Installation
No Gunsmith Needed
You don’t need an armorers bench or a YouTube tutorial. Just:
- Slide it on the rail
- Tighten it down
- Flip it up and go
Step-by-Step Mounting Instructions
- Align sight with the top rail
- Secure using flathead or Allen key
