It's a revolution in how you think about attaching your suppressor.
Muzzle thread adaptor system for A-TEC A-Lock compatible suppressors.
This product page is for the A-LOCK muzzle adaptor only.
- Threads 15x1 or smaller use the short A-Lock.
- Threads 16x1 and larger use the long A-Lock.
This unit can be used in two ways:
- Adaptor locked on to the muzzle thread
- This allows our suppressors 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.
- Adaptor locked inside the suppressor
- This allows the suppressor to be attached using muzzle threads like any conventional suppressor.
- When the suppressor is removed, nothing is left on the barrel thereby leaving its aesthetic unchanged.
Thread systems available in variant selector
- All usual imperial threads.
- All usual metric threads.
- Custom Thread (stainless steel adapter -not blued) -let us know the desired thread pitch in the notes on checkout.
ATTACHMENT INSTRUCTIONS
We recommend using a gunsmith to check your muzzle thread concentricity, dimensions and alignment before fitting. We also recommend having as large a thread diameter as possible on your barrel, i.e. don't just get a 1/2"x20 thread, it's unsuitable for most calibres other than 22LR.
- 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.
