LMT Defense 3 Prong Flash Hider Restrictor Cap 5.56mm - SKU: R-EC556RFH - UPC: 850076573096
Product Description
The LMT (Lewis Machine & Tool) R-EC556RFH is a specialized 3-prong flash-hiding restrictor end cap engineered specifically for 5.56mm / .223 caliber LMT suppressor systems. Designed to minimize flash output and eliminate secondary gas ignition, this end cap incorporates three precision-machined front tines that disrupt escaping muzzle gas patterns to eliminate night-vision blooming and visual optical signatures in low-light environments.
Precision CNC-milled from high-strength stainless steel alloys and treated with a heavy-duty, heat-resistant black finish, the R-EC556RFH handles intense thermal cycles, high pressure spikes, and sustained firing schedules. Its 5.56mm-calibrated restrictor aperture balances flash suppression efficiency with backpressure management, ensuring clean extraction and reliable weapon cycling.
Featuring precision wrench cuts around its outer diameter, the LMT R-EC556RFH allows for easy bench installation, tool-assisted removal, and routine suppressor maintenance without marring body threads.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits 5.56mm / .223 caliber LMT suppressors equipped with threaded, removable front end caps. Restricted strictly to 5.56mm NATO / .223 Remington projectiles and smaller. Do not use with larger calibers.
- Verify host firearm is completely clear, magazine removed, and chamber visually and physically confirmed empty.
- Ensure the silencer assembly is completely cool to the touch before performing end cap service or replacement.
- Unscrew and remove the existing front end cap using an approved LMT armorers tool or spanner wrench.
- Clean internal suppressor body threads with a brass wire brush and light solvent to remove copper and carbon fouling.
- Apply a thin layer of high-temperature anti-seize compound to the threads of the R-EC556RFH end cap, thread in hand-tight, and snug with the wrench. Always verify bore clearance using a 5.56mm alignment rod prior to live-fire.
Key Features
