LMT Defense 5.56 END CAP FOR MAX SOUND RED - SKU: R-EC556RES - UPC: 850076573072
Product Description
The LMT (Lewis Machine & Tool) R-EC556RES is a high-performance replacement front end cap engineered specifically for 5.56mm / .223 caliber LMT suppressors. Designed to achieve maximum sound reduction and decibel stripping, this cap features a tight, caliber-optimized exit aperture that restricts escaping muzzle gases, forcing a higher volume of expanding gas back through the internal baffle stack.
Precision CNC-machined from high-strength stainless steel alloys and coated with a durable, heat-resistant black finish, the R-EC556RES easily copes with heavy firing schedules, extreme thermal expansion, and intense pressure spikes. By tailoring the front aperture strictly to 5.56mm / .223 projectiles, it significantly attenuates impulse noise at the shooter's ear compared to oversized multi-caliber exit caps.
Featuring precision wrench cuts around its perimeter, the LMT R-EC556RES permits simple bench installation, tool-assisted removal, and routine suppressor maintenance without risk of 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-EC556RES 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
