Product Overview

The LBE Unlimited Flash Hider with Crush Washer delivers unmatched flash suppression for .308 Winchester AR‑15 rifles. Featuring a classic birdcage design, this muzzle device reduces muzzle flash to a minimum while maintaining excellent accuracy and low recoil impulse. The integrated crush washer ensures a secure, repeatable fit on any AR‑15 barrel that meets the standard 1.058‑inch (26.8 mm) diameter, making installation quick and hassle‑free.

Key Features & Benefits

• Birdcage Flash Suppression: 12 precisely‑machined slots create a uniform gas escape pattern, dramatically reducing visible flash in low‑light conditions.
• Crush Washer Installation: Eliminates the need for set‑screws or torque tools; the washer expands under pressure to lock the device firmly in place.
• Durable Construction: CNC‑machined 7075‑T6 aircraft‑grade aluminum provides a lightweight yet rugged solution that resists corrosion and wear.
• Zero Shift Design: Engineered to maintain point‑of‑aim (POA) after installation, preserving the rifle’s original accuracy.
• Low Recoil Impulse: Optimized port geometry reduces felt recoil, enhancing follow‑up shot speed.
• Universal Fit: Compatible with any AR‑15 barrel chambered in .308 Winchester that uses the standard 1.058‑in. (26.8 mm) outer diameter.
• Easy Maintenance: Smooth internal surfaces prevent carbon buildup; the device can be cleaned with a standard brass brush.

Compatibility

This flash hider is specifically engineered for the AR15 ARA2FH‑308 model but will also fit any AR‑15 platform chambered in .308 Winchester that adheres to the standard barrel dimensions.

• Caliber: .308 Winchester (7.62×51mm NATO)

Installation Instructions

1. Ensure the barrel is clean and free of oil or debris.
2. Place the flash hider onto the threaded barrel, aligning the slots with the barrel’s gas ports.
3. Thread the device by hand until it is snug.
4. Using a torque wrench set to 30‑35 in‑lb, tighten the crush washer. The washer will expand and lock the hider securely.

For optimal performance, re‑torque the crush washer after the first 100 rounds.
