A-Tec A-lock 5/8×24 is a suppressor mounting adapter, allowing quick installation and translation of the discharge device to another weapon.
A-Tec A-lock - suppressor mounting adapters and accessories
The adapter comes in several length versions and is screwed directly onto the barrel thread. Thanks to the side bolts, attaching the exhaust device to the barrel with the A-Lock adapter takes a few seconds and requires no tools. All you have to do is put the suppressor on and rotate it 60° using similar force/torque as with regular threads. If you have several gun units equipped with A-Lock adapters, you can quickly and conveniently rearrange and mount the suppressor/exhaust brake on another unit even while hunting. The adapter is mounted on a barrel with 5/8×24 thread.
Note that the A-LOCK adapter must be properly mounted on the barrel of the weapon, so it is recommended that the installation be done by a qualified gunsmith.
