TRI-LUG M18x1 Adapter

The adapter allows quick and reliable installation of suppressors with a TRI-LUG mounting interface, which is standard on firearms from Heckler & Koch, Brügger & Thomet and others.

The TRI-LUG Wrench is included in the package.

TRI-LUG ADAPTER INSTALLATION INSTRUCTIONS

1. Make sure the firearm on which you are going to install the adapter is unloaded and in a safe condition.
2. Remove the existing muzzle device.
3. Secure the firearm by the barrel, taking care not to damage it and ensuring that it cannot rotate while the adapter is being tightened.
4. Apply a small amount of thread-locking compound to the adapter thread (optional).
5. Screw the adapter onto the barrel thread and tighten it using the TRI-LUG Wrench to a torque of 15–20 ft-lb (20–27 Nm).

The recommended torque values are indicated on the TRI-LUG Wrench. The wrench features two square drive openings for 1/2" and 3/8" ratchets.

CAUTION: Do not exceed the recommended tightening torque. The TRI-LUG adapter and TRI-LUG Wrench are made from high-quality materials, and excessive tightening force could damage the thread at the muzzle of the barrel.
