Abstract: A firearm sight, optionally having a 45° offset mount, including a sight element selectively configurable in upright position and down positions, and a moveable plunger configurable in a locking mode in which a head of the plunger protrudes from it such that upon rotation of the sight element about a pivot axis, the head engages a plunger wall of the mount to arrest such rotation to thereby maintain the sight element substantially in the upright position, the plunger alternatively configurable in a free mode in which the head is retracted into the sight element so the head clears the plunger wall and the sight element can move to the down position. The mount can include an extension stop wall adjacent the head so the head cannot be deployed from the sight element to maintain it in the down position. The plunger can be actuated ambidextrously. A related method is provided.

Abstract: A rail insert is disclosed. The rail insert includes a backing member, at least one locating pin connected to the backing member, and at least one locking pin connected to the backing member. The backing member has a rail side and a grip side. The at least one locking pin has at least one compressible member.

Abstract: An apparatus is disclosed. The apparatus includes a base member and at least one support member. The base member includes an outer side surface and at least one support-member-receiving channel formed in the outer side surface. The at least one support member is pivotably-coupled to the base member for selective arrangement relative the base member in one of a stowed orientation and a deployed orientation. The at least one support member includes a surface geometry dimension that corresponds to a spatial dimension of the at least one support-member-receiving channel such that: upon arrangement of the at least one support member in the stowed orientation, an outer surface of the at least one support member is aligned with the outer side surface of the base member, and upon arrangement of the at least one support member in the deployed orientation, the base member in combination with the at least one support member forms a pod. A method is also disclosed.

Abstract: A firearm handguard assembly attachable to a receiver of a barrel of a firearm is disclosed. The firearm handguard assembly includes a barrel nut member, a locking sleeve member, a firearm handguard member and a plurality of fasteners. The locking sleeve member is disposed within an axial passage formed by the barrel nut member. A plurality of radial passages of the locking sleeve member are aligned with a plurality of radial passages of the barrel nut member. The firearm handguard member is arranged about the barrel nut member and the locking sleeve member such that the barrel nut member and the locking sleeve member are arranged within an axial passage of the firearm handguard member. The plurality of fasteners join the firearm handguard member to the barrel nut member and the locking sleeve member.

Abstract: An apparatus is disclosed. The apparatus includes an adapter including a first body and a second body. A lower surface profile of the first body and the second body cooperate to form a first geometric mounting profile. An upper surface profile of the first body and the second body cooperate to form a second geometric mounting profile. The first geometric mounting profile is different from the second geometric mounting profile. Each of the first body and the second body forms at least one first aligned bore that receives a first fastener that connects the first body to the second body and a spring that biases the first body and the second body away from one another. An assembly is also disclosed. A method is also disclosed.
