A-TEC A-LOCK MINI ADAPTER

$150.00

THE A-LOCK SYSTEM

A-LOCK MINI changes how you attach and detach your silencer. It changes what you look for in a silencer and it will change your view on threads. You want a silencer with A-LOCK mini: The greatest little thing A-Tec have ever made.

With A-LOCK mini you attach and detach your suppressor with a short 60 degree twist using similar amount of force/torque as with regular threads. It takes literally less than a second. The durable design withstands wear and tear better than regular threads.

The A-Lock system is a great way to use one suppressor on multiple barrels that all have different threads. 

The A-Lock is locked onto the muzzle thread with strong bonding compound and stays with that barrel. The A-Lock capable suppressor can then be applied at will.

½”-20 UNF | ½”-28 UNEF | 5/8”-24 UNEF | 3/4"-24

Fitting instructions, you can do this procedure with no special tools:

  • Thoroughly clean and degrease the rifle muzzle thread. Use brakeclean to get rid of any oil.
  • Thoroughly clean and degrease the a-lock adaptor inside thread, it’ll have factory oil in there.
  • Test the threads by winding the A-Lock onto the muzzle thread until it meets the thread shoulder.
    • Do not do it up tight! (yet)
    • It should fully contact the thread shoulder nice and square. This is the surface it contacts to ensure it is square.
      • This assumes the thread on the barrel is within specification. If it is oversized, it will be difficult to wind the A-Lock right up to the shoulder.
    • It should not bind on the small shaft section in between the thread and the shoulder.
    • With the A-lock firm against the shoulder, the rifle muzzle thread must not protrude beyond the front edge of the A-Lock. If it protrudes, it prevents correct locking of the A-lock into the suppressor.
    • DO NOT PUT THE SUPPRESSOR ON THE A-LOCK YET. IT WILL GET STUCK IN THE SUPPRESSOR.
  • Remove the A-lock.
  • Apply correct lock compound to the rifle threads. Personally I’m pretty copious with this.
    • Loctite 638 or Permabond A1046
  • Wind the A-Lock onto the muzzle thread fully home. Tighten up the A-Lock as tight as you can, just with your hands.
  • Wipe away excess thread lock. Ensure there is zero thread lock on the outside of the A-lock and muzzle crown.
  • Apply grease or viscous oil to the OUTSIDE of the A-lock.
  • Apply the suppressor to the A-lock. Only turn it ON to the threads, do not turn it OFF the threads to avoid unwinding the a-lock beneath. “On” is clockwise when viewed from muzzle to butt. You sometimes get a satisfying clunk when it is home.
  • Use hand pressure to tighten the suppressor onto the A-lock as hard as possible by hand. This is also applying torque to the A-Lock on the threads to tighten it against the shoulder. Tools to add extra torque are not necessary.
  • Leave the rifle overnight for the locking compound to cure completely.
  • Now remove the suppressor from the A-lock by turning it off (anti clockwise when viewed from the front).
  • Pop it on and off a few times.
  • And lastly the common sense safety check is to: apply the suppressor, look through the barrel from the action end and check for obvious malignment. It’s not a detailed precision check unless one’s eye is trained.
