Description

OBJECT OF THE INVENTION

The present invention relates to a muzzle brake-suppressor assembly for firearms which allows carrying out the coupling/uncoupling of the suppressor with respect to the firearm in a silent manner, without mechanical sounds, due to the presence of a system of anchoring the suppressor to the firearm which arranges the suppressor such that it is centered with the barrel of the weapon.

The system of anchoring the suppressor to the firearm allows the coupling/uncoupling of the suppressor to be carried out by means of a single operation, in a rapid manner and with one hand.

The invention also relates to a method of assembling a muzzle brake-suppressor assembly in a firearm.

BACKGROUND OF THE INVENTION

Muzzle brake-suppressor assemblies for firearms comprising a suppressor element which can be fixed or is fixed to the barrel element, wherein the suppressor element is fixed to the barrel element by means of at least one securing element external to the muzzle brake-suppressor assembly, are known in the state of the art.

Included among the prior art is European patent application EP3023729A1, wherein the external securing element is axially secured against at least one seating element formed integrally with the barrel element or fixed captively thereto, where the securing element can be fixed or is fixed inside the suppressor element.

These systems make it necessary to use external elements which complicate tasks of assembling and disassembling the suppressor with respect to the muzzle brake of the barrel.

Additionally, these systems have problems as regards misalignments of the suppressor with respect to the barrel, which results in the course of shots being altered due to said coupling.

The muzzle brake-suppressor assembly for firearms and the method of assembling a muzzle brake-suppressor assembly in a firearm of the present invention have a configuration and steps which allow solving all the aforementioned drawbacks because it is possible to carry out a coupling/uncoupling of the suppressor on the weapon in a silent manner, without mechanical sounds, where the suppressor is arranged such that it is centered with the barrel of the weapon.
