Frequently Asked Questions

You will need a collar to mount any Allen Engineering reflex suppressor. There are many collar options you can choose from. For an overview of all of them click here. 

For brake mounted suppressors you should have 7-10 turns. For direct thread suppressors you should have a minimum of 7 turns. For more information click here.

The 5.56 and .30cal muzzle devices are functionally the same since they both share the M22x1 external thread pitch. This means any Allen Engineering suppressor can mount on any OPS/AE muzzle device. 

However the bore size of the muzzle devices do not allow .30cal or 6mm rounds to be shot from a 5.56 brake. You can shoot 5.56 from the .30cal brake.

Simply, any AEM5 variant (5-30, 5k, 5-30k) will all share the same mounting style (A-Mount). The newer AEM suppressors (2, 3, 4) will all share the same mounting style (B-Mount). Direct thread suppressors (M4, M24) have their individual mounting styles. For more information click here.

They are functionally the exactly the same, it just comes down to how you want to time your muzzle device. So if you are struggling figuring out which one will work for your setup, they will both work. The only difference is that one uses a crush washer and the other uses shims.

We currently do not make a suppressor to fit over a 16″ FSB barrel. Our current options are to use a 14.5″ FSB barrel with the M4 suppressor or a 12.5″ with an AEM5. Click here for more information.
