Guntec AR15 Stainless Steel Crush Washer

Guntec AR15 Stainless Steel Crush Washer

A crush washer is an essential component for any AR15 builder or armorer. This stainless steel washer serves a critical function: it allows you to time your muzzle device—whether a flash hider, muzzle brake, or compensator—to the correct rotational position while maintaining proper headspace.

Key Features

• Stainless steel construction for corrosion resistance and durability
• Precision engineered to work with standard AR15 muzzle devices
• Crushable design that deforms slightly during installation to lock your muzzle device in the correct orientation
• Essential for proper timing of flash hiders and muzzle brakes

Why It Matters

Proper muzzle device timing affects flash signature, recoil management, and overall rifle performance. A crush washer ensures your device is installed at the optimal angle. The stainless steel construction resists corrosion from powder residue and environmental exposure, making it a reliable choice for both range shooters and field use.

Installation Note

This is a consumable item—it's designed to be crushed during installation and typically replaced if you need to remove or change your muzzle device. Keep a few on hand for future builds and maintenance.
