TROY Front Folding M4-Style BattleSight – Black (AR-15/1913)
Model: SSIG-FBS-FMBT-00 • UPC: 812699010686
Trust your irons when it matters. The TROY Front Folding M4-Style BattleSight (Black) is the industry-standard AR-15 front BUIS for shooters who want rugged reliability, precise adjustments, and a snag-free profile that disappears until you need it. Built to TROY’s hard-use spec from aircraft-grade aluminum with stainless steel hardware and a mil-spec hard-coat anodized finish, this Picatinny 1913 front sight locks solidly in the upright position and folds low-profile to clear optics, magnifiers, and night-vision devices.
The classic M4-style protected front post gives you familiar sight pictures and repeatable elevation clicks—so you can zero fast, co-witness with your optic, and hold that zero through recoil, weather, and hard field use.
Why This TROY BattleSight Stands Out
Folding, Low-Profile Design
Drops flat when stowed for an uncluttered optic view and quick transition to red dots, LPVOs, and NV devices. Deploys in an instant with positive detent lockup.
M4-Style, Protected Front Post
Robust protective ears shield the post from impacts while providing a clean, familiar iron sight picture.
Precise Elevation Adjustment
Standard A2 front sight post with crisp detents for repeatable elevation—adjust with a front sight tool or the tip of a cartridge.
Hard-Use Construction
6061-T6 aluminum body, stainless steel pivot/fasteners, and Type III hard-coat anodizing in matte black for corrosion resistance and duty-grade durability.
Same-Plane Rail Height
Engineered for receiver-height Picatinny rails, so the front sight aligns with a receiver-height rear sight for consistent zero.
Co-Witness Friendly
Pairs with popular red-dot heights for absolute or lower 1/3 co-witness (depending on your optic mount), giving you instant backup without re-zeroing.
Key Specifications
Brand / Series: TROY Industries – Front Folding M4-Style BattleSight
Model: SSIG-FBS-FMBT-00
UPC: 812699010686
Color / Finish: Black, matte Type III hard-coat anodized
Material: Aircraft-grade aluminum with stainless steel hardware
Mounting Interface: MIL-STD-1913 Picatinny (receiver-height / same-plane)
Adjustment: Elevation at front post (A2-style detents); windage adjusted at the rear sight
Profile: Folds to a low-profile stowed position; locks in the up position
Compatibility: AR-15/AR-pattern uppers and any firearm with receiver-height Picatinny top rails
Fit Note: This sight is designed for same-plane receiver-height rails. It is not for low gas-block rails that sit below receiver height. For railed gas blocks, use a gas-block-height front sight.
Performance Benefits You’ll Notice
Always There, Never in the Way
Run your optic as primary and keep irons folded until needed. If your dot fails, flip up the TROY front and your rear BUIS and drive on.
Fast, Familiar Zero
Use a standard A2 tool to dial elevation on the front post. Crisp detents deliver repeatable clicks for fast initial zero and easy field corrections.
Built to Stay Zeroed
The robust hinge and detent system resist play and maintain return-to-zero—even after repeated deploy/stow cycles and sustained recoil.
Ideal Use Cases
Duty / Defensive Carbines – Proven BUIS that locks up solid when it counts
Competition & Training – Reliable irons for rule-sets that require mechanical sights
General Purpose AR Builds – Clean, professional look with true hard-use durability
Night-Vision / Magnifier Setups – Stows flat under or behind optics without clutter
Installation & Zeroing (Quick Start)
Safe & Clear: Verify firearm is unloaded.
Mount: Place on receiver-height Picatinny rail, forward of the rear sight. Tighten per TROY’s torque guidance (use thread locker per best practices).
Co-Witness Check: Confirm absolute or lower 1/3 co-witness based on your optic mount.
Zero: Adjust elevation at the front post (down = POI up; up = POI down). Make windage on your rear sight. Confirm at 25/50 yards (or your preferred zero).
Care & Maintenance
Keep Threads Tight: Periodically verify clamp screws for torque; a touch of blue thread locker helps.
Clean After Weather: Wipe moisture and debris; add a light protectant to metal surfaces.
Protect Detents: Avoid excessive oils that attract grit around the hinge/detent.
Frequently Asked Questions
Q: Will this fit my AR-15 handguard rail?
A: Yes—if the handguard rail is receiver-height (same plane as the upper receiver). It will not align on lower gas-block rails.
Q: Is it spring-assisted?
A: The sight folds and locks with a robust detent system for secure up/down positions and one-hand operation.
Q: How do I adjust windage?
A: Windage is set at the rear sight. The front post adjusts elevation.
Q: Can I co-witness with a red dot?
A: Yes. With a receiver-height mount, you’ll achieve absolute or lower 1/3 co-witness depending on your optic mount height.
Q: Is the front post replaceable?
A: The sight uses a standard A2-style post, making replacements or upgrades straightforward.
