US12736297 - Muzzle device adapter system

Subject matter related to firearms is described. An adapter may include a channel that extends along an exterior of the adapter in a helical pattern. The helical pattern may be configured to advance the adapter into a complementary component based on a rotation of the adapter, the complementary component, or both. Based on the advancement of the adapter into the complementary component, a sidewall of the channel may be forced against a sidewall of a ridge of the complementary component. The channel may lock with the ridge based on a rotation of the adapter, a rotation of the complementary component, or a combined rotation of the adapter and the complementary component that is less than 180 degrees.

Claim 1

1 . A firearm accessory adapter comprising: a body having a front end opposite a rear end and a longitudinal axis extending from the front end to the rear end; a plurality of ridges extending from an exterior circumference of the body, each ridge having a front face and a rear face; a channel formed on the exterior circumference of the body, the channel having a substantially continuous rear sidewall and a front sidewall defined by the rear faces of the plurality of ridges, the front sidewall having a plurality of openings between the plurality of ridges; a central bore; and an annular face at the front end; wherein the channel is configured to receive one or more interior ridges of a firearm accessory through one or more of the plurality of openings in the front sidewall, and is further configured such that rotation of the firearm accessory relative to the firearm accessory adapter draws the received one or more interior ridges toward the rear end and forces the one or more interior ridges into contact with the substantially continuous rear sidewall; wherein the channel is further configured to draw the one or more interior ridges into a locked configuration with less than 180 degrees of rotation of the firearm accessory relative to the firearm accessory adapter; and wherein, when the one or more interior ridges are in the locked configuration, the annular face is seated against an interior annular ledge of the firearm accessory. a body having a front end opposite a rear end and a longitudinal axis extending from the front end to the rear end; a plurality of ridges extending from an exterior circumference of the body, each ridge having a front face and a rear face; a channel formed on the exterior circumference of the body, the channel having a substantially continuous rear sidewall and a front sidewall defined by the rear faces of the plurality of ridges, the front sidewall having a plurality of openings between the plurality of ridges; a central bore; and an annular face at the front end; wherein the channel is configured to receive one or more interior ridges of a firearm accessory through one or more of the plurality of openings in the front sidewall, and is further configured such that rotation of the firearm accessory relative to the firearm accessory adapter draws the received one or more interior ridges toward the rear end and forces the one or more interior ridges into contact with the substantially continuous rear sidewall; wherein the channel is further configured to draw the one or more interior ridges into a locked configuration with less than 180 degrees of rotation of the firearm accessory relative to the firearm accessory adapter; and wherein, when the one or more interior ridges are in the locked configuration, the annular face is seated against an interior annular ledge of the firearm accessory.
