A mount for mounting a firearm sound suppressor or silencer to a firearm muzzle or muzzle device operates by using primary mounting lugs on the suppressor which engage sockets on the muzzle device. The primary lugs prevent the suppressor from axially moving with respect to the muzzle device, thus causing them to be fixed together as a unitary device. Angled bearing faces on the muzzle device and the sound suppressor are pressed against each other by rotating the sound suppressor on threads which drive the angled bearing faces together, thus tightening the primary lugs within their sockets. Backup lugs on the silencer engage an annular groove on the muzzle device to retain the silencer on the firearm to which it is mounted in case of failure of the primary lugs. Rapid attachment and detachment are supported by these structures.

A firearm suppressor also known as a moderator includes a number of coaxially joined steel baffles for dissipating discharge gasses. Each baffle can have an internal funnel structure having a central aperture through which the firearm projectile passes. Adjacent funnel structures form interconnected primary and secondary chambers connected by a port through a flange separating the chambers. A notch in the central aperture of one funnel structure directs flow toward the port on the diametrically opposite side of the next funnel structure. A radial hole through the funnel structure connects successive primary and secondary chambers. The flange is axially located to be radially inward from an overlapping joint between two adjacent baffles in order to provide structural support to the joint.

A firearm sight assembly comprises a rear base. The firearm sight assembly comprises a rear sight element movable with respect to the rear base between a lowered condition and an elevated condition. The rear sight element has a first pair of upwardly projecting first rear posts defining a first notch therebetween when in the lowered condition. The rear sight element has a second pair of upwardly projecting second rear posts defining a second notch therebetween when in the elevated condition. The first rear posts extend to a first height above the rear base, and the second rear posts extend to a second height above the rear base. The second height is greater than the first height.
