Strike Industries AR Dust Cover — .223/5.56, FDE (Flat Dark Earth)
Model/SKU: SI-AR-UDC-E-TX-223-FDE | Alt SKU: ARUDCETX223FDE | UPC: 793811765816
Upgrade your rifle’s ejection port with a cleaner, quieter, and tougher solution. The Strike Industries AR Dust Cover (.223/5.56) in FDE is an Enhanced UDC that replaces the traditional sheet-metal door with a precision-molded cover designed for tool-less installation, reliable sealing, and long-term durability. The Flat Dark Earth finish pairs perfectly with modern FDE builds while protecting your action from grit, sand, dust, and weather on the range, in training, or out in the field.
Why This Strike Industries Dust Cover Stands Out
Tool-less, ultra-fast installation: Drop it in and snap it on—no tiny C-clips to launch across the shop. Field swaps are actually doable.
Springless internal detent system: Eliminates the separate torsion spring/rod headache of Mil-Spec doors for smoother operation and fewer parts to lose.
Durable impact-resistant construction: Engineered polymer body resists dents, bends, rust, and corrosion that plague stamped steel covers.
Clean, low-profile design: Reduced rattle with a crisp open/close feel; improved fit helps keep crud out of your upper receiver.
FDE colorway: Flat Dark Earth matches popular FDE receivers, rails, stocks, and grips for a cohesive look on your AR build.

Compatibility Notes: Designed for Mil-Spec AR-15 upper receivers chambered in .223/5.56 (also commonly fits many .300 BLK uppers that use standard port dimensions). Not compatible with AR-10/LR-308 pattern receivers and some billet uppers with non-standard port geometry. Always compare your upper before installation.
Real-World Benefits You’ll Notice
Better protection: Helps keep fine dust, carbon, and debris from entering the action when closed—especially important during transport and in dusty environments.
Less noise & slop: Rigid polymer won’t “tin-can” like thin stamped steel doors; the door closes with a positive snap.
Maintenance made easy: Pop it off for cleaning without fighting a hinge rod or spring; re-install in seconds.
Weather resistance: Polymer body won’t rust; wipe it down and go.
Who It’s For
Builders finishing a premium FDE AR who want cohesive color and smarter parts.
Students & instructors who need easy field service and fewer micro-parts to lose during classes.
Duty & ranch rifles exposed to wind, dust, and grime where a sealed ejection port matters.
Competition shooters streamlining weight and snag points without sacrificing function.
Quick Install Guide
Unload & clear your firearm; separate upper and lower receivers.
Align the enhanced dust cover with the ejection port.
Snap in place: Engage the integrated hinge/detent following the included instructions—no tools or e-clips required.
Function check: Open/close the cover; confirm it pops open on bolt cycling and stays latched when closed.
Final wipe-down and you’re range-ready.
Pro Tip: After installation, cycle the bolt several times to verify positive auto-open behavior and check that the latch seats fully when closed.
Care & Maintenance
Wipe with a microfiber cloth and mild cleaner after dirty range days.
Inspect the latch surface and detent contact points periodically; remove excess carbon from the ejection port lip to maintain a solid seal.
