Daniel Defense Fixed Iron Sight Set - A1.5 Detachable Rear Sight & Low-Profile Front Sight, Rock & Lock Mounting System, Matte Black Anodized Finish - 19-088-09116
Product Description
Setting up a heavy-use tactical rifle with folding back-up sights often introduces accuracy compromises. Under hard field impacts or continuous rapid-fire heat strings, folding mechanisms can develop small amounts of hinge play, shifting your mechanical alignment and displacing your point of impact on your bench. The **Daniel Defense® Fixed Iron Sight Set (19-088-09116)** completely flatlines this alignment variable, providing a pair of rock-solid, ultra-rigid combat sights that bolt directly into place without any folding hinges.
Proudly engineered and precision CNC-machined from choice **6061-T6 structural aerospace aluminum billet**, this tactical indexing kit is finished in a non-reflective, scratch-resistant Mil-Spec Type III hardcoat anodized dressing. The **A1.5 fixed rear sight assembly** features a classic, intuitive dual-peep aperture system that allows for tool-free, fine windage indexing using standard dial clicks. The low-profile matching front tower includes standard serrations on the rear face to minimize sunlight glare and uses a traditional A2 front sight post. Both structures utilize Daniel Defense's proprietary **Rock & Lock® single-bolt mounting system**, ensuring the bodies sit dead-flat and snag-free along any standard top rail lane.
Arriving as a complete matching front and rear set that lines up perfectly with standard optical co-witness planes, this turn-key targeting asset delivers absolute combat reliability straight to your workbench.
*Armorer Bench Notes & Real-World Rail Staging Guidance: The Daniel Defense 19-088-09116 iron sight kit arrives pre-assembled as a matching two-piece set, featuring the fixed A1.5 rear sight tower, the low-profile front post assembly, and 2x high-tensile slotted steel cross-bolts. UNIVERSAL MIL-SPEC PICATINNY INTERFACE MATRIX: This combat sight set is engineered natively, strictly, and cross-compatibly to mount onto any standard **Mil-Spec 1913 Picatinny rail structure**. *Optoelectronic Staging Alignment:* Both sight decks are precision-cut to match the standard **Absolute Co-Witness height profile (~1.50-inch center line)**. When paired with standard red dot optics on baseline risers (like an Aimpoint® or Holosun®), the iron sights sit directly in the center of your optic window. Armorer Workbench Assembly Sequence: 1. Visually and physically confirm your rifle platform is completely unloaded, the magazine is separated, and the chamber is clear. 2. Clean your upper receiver and handguard top rail slots with a dry utility patch to wipe away shipping oils. 3. Position the A1.5 rear sight block as far back as possible on your upper receiver rail slots, typically over the last slot before the charging handle channel. 4. Position the front sight tower as far forward as possible along your handguard's top Picatinny rail lane to achieve the longest possible sight radius. 5. Engage the Rock & Lock attachment lips over the rail flank, ensure the cross-bolts line up cleanly within the rail grooves, and torque the slotted screws clockwise to exactly **20 to 25 inch-pounds (in-lbs)**. *Critical Torque Warning:* Over-tightening can strip the steel threads or mar your aluminum rail edges; use an authenticated torque driver tool downrange.*
