ABSTRACT:
A coupler for attaching a suppressor to a firearm flash hider. The coupler includes a main body, an inner collar, and an outer collar. The main body defines a through bore configured to closely receive the flash hider at one end and for the passage of the bullet at the other. The main body defines a first threaded portion proximate the central portion thereof, the threads being right-handed threads. The main body defines a sound suppressor attachment device at the second end thereof. The inner collar defines a through bore oriented coaxially thereto. A first end of the through bore is configured to receive the first end of the main body. Proximate the second end of the inner collar, the through bore defines a second inner diameter dimensioned to receive the firearm flash hider. The inner collar carries a plurality of locking fingers, each pivotally mounted on the inner collar via a pivot pin. When the inner collar is received over the flash hider, the fingers are pivoted toward the barrel in order to prevent axial movement of the flash hider with respect to the coupler. The inner collar also defines a threaded portion, the threads having a left-handed orientation. The outer collar defines an inner diameter configured to closely receive the main body first end and the inner collar. At a central portion of the interior of the outer collar, a first threaded portion is configured to cooperate with the first threaded portion defined by the main body. At the first end of the outer collar interior, a second threaded portion is configured to cooperate with the inner collar threaded portion.
