A-Tec A-Lock Thread Adapter | M15x1 Thread

Muzzle thread adaptor system for A-Tec Optima and H2 suppressors. It’s a revolution in how you think about attaching your suppressor.

Features for A-Tec A-Lock Thread Adapter | M15x1 Thread: 

• Adaptor locks on to the muzzle thread of rifle
• This allows the Optima and H2 suppressor to be quick attached and detached in a second with a forceful 1/4 turn.
• This allows a single suppressor to be shared amongst multiple rifles all with different threads. In this case the calibre of the suppressor must be equal or greater than the largest calibre rifle.
• This means the adaptor is on the end of the muzzle, maybe affecting it’s aesthetic if it is a thin barrel.

Instructions for A-Tec A-Lock Thread Adapter | M15x1 Thread:

• Check that the rifle is unloaded and remove the bolt from the action.
• Do not do a test run of attaching the adaptor and suppressor as the A-Lock will get stuck inside the suppressor.
• Degrease(brake clean) the threads on the A-LOCK Mini Adapter and on the barrel.
• Do a dry run of the adaptor onto the threads:
• Maximum length of the thread from muzzle to shoulder should be 15mm.
• Do not tighten at all, it could get stuck.
• Check there is ZERO protrusion of the muzzle crown or threads past the end of the adaptor. Protrusion will prevent the adaptor locking into the suppressor.
• Remove.
• Apply strong and heat resistant thread lock such as Loctite 638 to the muzzle threads on your barrel.Attach and tighten the A-LOCK Mini Adapter to the barrel by hand. Use a rag to get more purchase on the adaptor.
• Wipe off any excess Loctite adhesive, especially on the A-Lock outer surface and threads. Apply grease on the A-LOCK Mini Adapter.
• Attach the suppressor, turning it only in the locking direction so that it does not loosen the adaptor.
• Grasp the suppressor and tighten with moderate torque (6-8 Nm). Do not use extreme force, or the A-LOCK Mini threads may be damaged.
• Let the adhesive cure for 12-24hrs.
• After curing, detach and attach the silencer a few times to check the fitting and alignment.
