LBE Unlimited Crush Washer – For 7.62×39mm AK-47 Muzzle Devices
(Model AK47CW | UPC 706612408448)
Time and secure your AK muzzle device the easy way. The LBE Unlimited Crush Washer for 7.62×39mm AK-47 (AK47CW) provides a simple, single-use solution for aligning and locking brakes, comps, and flash hiders on AK-pattern rifles. Built from durable spring steel and finished in low-profile black, this crush washer deforms predictably as you torque the device, letting you fine-tune timing, protect the barrel shoulder, and achieve a snug, repeatable install—without stacks of shims or guesswork.
Whether you’re swapping the OEM slant brake for a modern compensator or building out a new upper with a pinned device, the AK47CW gives you the clean, reliable interface serious shooters expect.
Why Choose the LBE Unlimited AK47CW Crush Washer?
Correct Timing Made Simple
The crush washer’s controlled deformation allows precise indexing of ports and baffles for top-dead-center alignment—critical for recoil control and flash reduction.
Secure, Single-Use Lockup
Compresses under torque to create constant spring tension, helping resist loosening from heat cycles and recoil.
Protects Barrel Shoulder
Provides a sacrificial surface between your muzzle device and the barrel shoulder to help maintain clean contact and even pressure.
Low-Profile Black Finish
Blends with phosphate/nitride barrels and most device finishes for a non-reflective, OEM-style look.
AK-Pattern Focused
Designed specifically for 7.62×39 AK-47 builds and aftermarket devices that require a crush washer for final alignment. (Verify your muzzle thread pitch—many AKM/AK-47 barrels use 14×1 LH threads.)
Note: Standard AK brakes often rely on a detent and do not require a washer. For suppressor mounts or precision devices, manufacturers may recommend shim kits instead. Always follow your muzzle device maker’s guidance.
Key Specifications
Brand / Model: LBE Unlimited AK47CW
UPC: 706612408448
Caliber Class: 7.62×39mm (AK-47 pattern)
Use: Timing and securing muzzle brakes, compensators, flash hiders
Material: Spring steel, crush-type (single use)
Finish: Black, corrosion-resistant
Compatibility: AK-pattern barrels and devices that accept a crush washer (confirm thread pitch—commonly 14×1 LH on AKM/AK-47; some variants differ).
Performance Benefits You’ll Notice
Consistent POI & Control
Properly timed ports keep gas where it should be, improving muzzle rise control and reducing off-axis impulse for faster, flatter follow-ups.
Heat & Recoil Resilience
The compressed washer maintains tension through thermal expansion and vibration, helping the device stay put during long range sessions.
Clean Install, Clean Look
No stacked shims, no gaps—just a flush, uniform shoulder and a device that lines up exactly as intended.
Ideal Applications
Brake/Comp Upgrades: Replace the factory slant brake with modern ported or baffle designs.
Flash Hider Alignment: Ensure prongs/slots are indexed correctly for minimal signature.
Clone & Custom Builds: Achieve repeatable, professional muzzle installs on AK rifles.
Installation Overview (High-Level)
Verify Thread Pitch & Direction: Most AKM/AK-47 barrels are 14×1 LH (left-hand). Confirm your rifle and device specifications.
Prep Surfaces: Degrease barrel threads, device threads, and the barrel shoulder.
Seat the Washer: Slide the crush washer onto the barrel with the beveled face toward the muzzle device (typical orientation).
Hand-Thread the Device: Spin the device on by hand until it contacts the washer.
Time the Device: Using a properly fitted wrench, apply torque gradually (remember LH threads turn opposite) until ports index top-dead-center.
Final Check: Ensure full thread engagement, verify clearance, and confirm the device is square to the bore.
Important: Crush washers are single-use. If you remove the device, replace the washer before re-installing. For suppressor hosts, many manufacturers require shim kits or shoulder-register solutions instead of crush washers.
Care & Best Practices
Re-Torque Check: After the first range trip and heat cycle, verify the device remains timed and snug.
Don’t Over-Crush: Use steady, incremental torque—excess force can over-compress the washer and complicate future removal.
Follow Device Guidance: Some muzzle devices specify torque values or do not allow crush washers—always defer to the device manufacturer.
Frequently Asked Questions
Q: Will this work with my AK threads?
A: Most 7.62×39 AK-47 barrels use 14×1 LH threads, but some imports/variants differ. Check your barrel and device before purchase.
Q: Can I reuse a crush washer?
A: No. Crush washers are single-use by design. Replace any time the device is removed.
Q: Is this suitable for suppressors?
A: Generally no. Manufacturers usually require shims or precision mounts for suppressors. Follow your suppressor/mount instructions.
Q: My rifle has a detent on the FSB. Do I still need a washer?
A: Many factory AK brakes use the detent for retention and don’t need a washer. Aftermarket brakes/comps that specify a washer can use the AK47CW for timing.
Q: Which side faces the device?
A: Typically the beveled/cone side faces the muzzle device. Confirm orientation per the device maker’s instructions.
