TROY Industries 45-Degree Offset Folding BattleSight Set M4 Front & Dioptic Rear Black - SSIG-45S-MDBT-00
Product Description
Deploying a high-magnification rifle scope or a low-power variable optic (LPVO) gives tactical marksmen a distinct advantage at extended ranges, but it introduces a critical vulnerability during sudden close-quarters transitions. If a primary electronic optic fogs over, suffers battery failure, or an unexpected threat emerges inside room-clearing distances, adjusting your magnification dial or looking through a dark tube can cost valuable seconds. The TROY Industries 45-Degree Offset Folding BattleSight Set solves this operational bottleneck by providing an instantaneous, 1x mechanical aiming index that sits completely clear of your primary optics package, ensuring you are never blinded at close range.
Precision-machined from hardened aircraft-grade aluminum billet and reinforced with rugged stainless steel internal components, this premium backup iron sight (BUIS) set is engineered to withstand severe field impacts and heavy weapon recoil. The exterior is protected by a uniform, non-reflective mil-spec hardcoat anodized finish that shrugs off abrasive weather and harsh carbon fouling. This specific configuration features the iconic M4-style protected front post combined with TROY's advanced Dioptic diamond-shaped rear aperture. Unlike traditional round apertures, the diamond pattern leverages the human eye’s natural tracking mechanics to instantly center the front post within the intersecting corner coordinates, drastically accelerating reflexive target acquisition under high-stress conditions.
When stowed, these sights fold down into an exceptionally compact, low-profile configuration that rides just 0.50 inches above the rail, entirely clearing the physical footprint and adjustment turrets of large tactical optics. Upon deployment, a positive upward flip engages TROY's heavy-duty stainless steel cross-locking detent system, locking both towers upright with absolute zero-drift rigidity. Because the base is entirely ambidextrous, the sights can be mounted to track off either the right or left side of the receiver. Canting the rifle exactly 45 degrees yields an intuitive, factory-height sight alignment that allows operators to seamlessly manage close-range threats without breaking their master grip or shifting their cheek weld.
*Armorer Bench Notes & Technical Maintenance Guidance: The TROY 45-Degree Offset BattleSight set is engineered strictly for same-plane rail configurations. The front and rear sights must be mounted to a continuous, uniformly leveled Picatinny rail structure; they will not align correctly if the front sight is attached to a railed gas block that sits lower or higher than the receiver rail. Secure the cross-bolts to a torque specification of 25–30 in-lbs using a drop of medium-strength thread locker to prevent backing out from heavy thermal expansion. Windage is fully adjustable on the rear assembly via the detent wheel, while elevation adjustments are dialed in at the front post using a standard A2 sight tool. Periodically clear the cross-locking hinge points of dirt or carbon grit using a nylon brush and a light drop of dry-film lubricant to maintain a crisp, snap-open deployment action.
Key Features
- 45-Degree Offset Mounting: Positions the backup irons offset from the primary optical plane, enabling lightning-fast sight transitions with a simple 45-degree roll of the wrist.
- Dioptic Rear Design: Utilizes an advanced diamond-shaped aperture structure that naturally forces the human eye to track and center the front post faster than circular openings.
- Hardened Aircraft Aluminum: Built from premium aerospace aluminum and mil-spec hardcoat anodized to maximize structural integrity without overloading the rifle's handguard.
- Cross-Locking Detent System: Equipped with a heavy-duty stainless steel lockup mechanism that ensures the sights remain upright and tracking straight under heavy tactical use.
- Ultra-Low Stowed Profile: Folds flat to a height of under half an inch, preventing any snagging risks or interference with bulky primary optic turrets.
