HERA Link System PEPPER-BOX up to 9 mm Luger (MPB9)

Available directly from our warehouse. Pay attention to the respective delivery time information.

The Link System from Hera Arms offers a modular and simple way to mount and change muzzle attachments. The system consists of two parts – the base holder, which is screwed onto the muzzle thread of the firearm and remains there, and the muzzle attachment, which is simply screwed into the base holder and aligned and fixed with 3 set screws in the style of a three-jaw chuck.

The muzzle attachments come in various versions, but of course all models can be easily mounted in the base holders – after all, that is the principle of this system. When used with a suppressor, it is important to choose the appropriate muzzle attachment – Hera Arms recommends using the muzzle attachments MBS (Muzzle Brake Short) or PB (Pepperbox) for optimal suppressor function. If the muzzle attachment is too long, the suppressor may not be mountable.

When choosing the muzzle attachment, it is ABSOLUTELY necessary to select the correct caliber!
A muzzle attachment .30 can be used with a .223 firearm but NOT vice versa!
A suppressor/firearm combo in .223 can be used with a muzzle attachment .30 but NOT vice versa!

The new HERA Link System at a glance - examples:

Mounting the Link System:

The base holder is screwed directly onto the corresponding muzzle thread.

Please do not use crush washers or washers!
Applying thread locker is not necessary.


The base holder is firmly screwed against the barrel – proper clamping of the firearm is essential.
Before mounting the muzzle attachment, make sure that the 3 set screws in the base holder are screwed out enough so they do not block the muzzle attachment!
The chosen muzzle attachment is first screwed into the base holder as far as possible and then aligned – for this, it is unscrewed just enough until the compensator holes are in the desired position.
The two parts are fixed against each other by tightening the 3 set screws in the base holder.

The screws should first be lightly tightened one after the other and finally tightened by hand.
When using the SD base holder, make sure the set screws do not block the M27x1.5mm thread – however, this should be impossible when fixed.
If the set screws protrude beyond the body of the base holder when fixed, the muzzle attachment was not mounted properly or there are foreign objects in the construction.


If the muzzle attachment is to be changed or the system cleaned, the 3 set screws must of course be loosened first so the muzzle attachment can be removed.
We generally recommend having the mounting performed by a knowledgeable person.
