Daniel Defense Rail-Mounted Fixed Front Sight — Black Hardcoat Anodized | Model 190170413 | UPC 852548002172
Bombproof Simplicity You Can Trust
When electronics fail or timelines get tight, iron sights keep you in the fight. The Daniel Defense Rail-Mounted Fixed Front Sight (model 190170413) delivers the rugged reliability and zero-retaining consistency that shooters demand. Machined from durable aluminum and finished in a matte black hardcoat anodize, this fixed front sight mounts securely to any MIL-STD-1913 Picatinny top rail on the same plane as your receiver. The robust protective ears shield the post from hard knocks, while the classic A2-style elevation-adjustable post provides precise, repeatable adjustments at the range or on duty.
Pair it with a Daniel Defense or other AR-height fixed/flip rear sight for an industry-standard sight picture and dependable co-witness with common red dots.
Key Features at a Glance
Fixed Front Sight: Always ready—no buttons, no hinges, no failure points
Rail-Mounted: Fits MIL-STD-1913 Picatinny top rails on same-plane handguards/uppers
Material & Finish: Hard-use aluminum with black hardcoat anodized finish for corrosion and wear resistance
Protected Post: Sturdy protective ears defend zero from bumps, barricades, and truck duty
A2-Style Post: Elevation adjustable with standard sight tools; tactile detents for repeatability
AR-Height Geometry: Designed to align with common AR-pattern rear sights and co-witness red dots
Low Profile, Light Weight: Adds minimal bulk while providing a crisp, uncluttered sight picture
Model / UPC: 190170413 / 852548002172
Fit note: Use on a same-plane rail system (receiver-height handguard). Not intended for railed gas blocks that sit lower or higher than receiver height.
Why This Sight Stands Out
Proven Durability
The hardcoat anodized finish shrugs off weather, sweat, and solvent. Precision machining and robust cross-bolt clamping keep the sight locked, even after long training cycles and vehicle transport.
Always-On Assurance
Fixed irons eliminate deployment steps under stress. Your sight picture is up the instant you shoulder the rifle—no levers, no guesswork, just point, confirm, press.
Precise, Familiar Adjustments
The A2 post gives you fine elevation control with positive clicks. Zero it once, verify periodically, and rely on a sight line that doesn’t wander.
Optimized for Co-Witness
Set for standard AR sight height, the sight co-witnesses with popular micro red dots on absolute or lower-third mounts (depending on your setup), giving you redundant aiming systems without clutter.
Ideal Use Cases
Duty & Defensive Carbines: Non-electronic redundancy that retains zero
Training & Classes: Bombproof irons for fundamentals, diagnostics, and backup
Competition: Always-ready reference sighting in rain, mud, or prop-heavy stages
General Purpose Builds: A no-nonsense front sight that matches quality rear irons
Installation & Zeroing Tips
Mounting: Place on a same-plane Picatinny rail section with the protective ears vertical; torque per manufacturer guidance.
Alignment: Ensure the sight sits square to the bore; verify no front handguard flex interferes.
Zero: Use standard AR zero procedures (e.g., 50/200 or 36/300). Adjust elevation at the front post, windage at the rear.
Thread Care: A small amount of non-permanent thread locker on the clamp fastener helps maintain torque under recoil.

FAQ
Q: Will this work on my railed gas block?
A: Use it on same-plane rails (receiver-height handguard/upper). Railed gas blocks often sit lower/higher than receiver height and will not align correctly.
Q: How do I adjust elevation?
A: Rotate the A2 front sight post using a sight tool or the tip of a cartridge; detents ensure precise, repeatable clicks.
Q: Does it fold?
A: No—this is a fixed front sight for maximum readiness and durability.
Q: What rear sight should I pair it with?
A: Any AR-height rear sight—fixed or flip—will align. Many users pair it with a Daniel Defense fixed rear sight.

Responsible Use Reminder
Confirm torque, verify zero, and perform regular inspections after hard use. Iron sights provide critical redundancy—practice with them so they’re second nature when you need them.
