Quick disconnect sling mount for a firearm
A quick disconnect assembly for a sling mount includes a cup having a top portion and a shaft portion connected to the top portion, the cup defining a non-circular through-opening and a recess that extends axially part way into the shaft portion. A post includes a post body extending axially between a first end portion and a second end, the first end portion having one or more protrusions. The post is configured to pass through the through-opening in the cup when the post is in an unlocked position with the protrusion(s) aligned with the through-opening. Rotating the post to a locked position aligns the protrusion(s) with the recess, which can define a plus shape with the through opening. A mounting body on the second end of the post defines or can include an attachment point. A spring is on the post between the mounting body and the cup.

8 . The quick disconnect assembly of claim 1 , wherein the attachment point and the post comprise a single monolithic structure.
9 . The adjustable stock of- claim 1 , wherein the receptacle is part of a hand guard for a long gun.
10 . The of claim 1 , wherein the quick disconnect assembly is provided in a disassembled form.
11 . A handguard for a long gun, comprising:
a quick disconnect assembly for a sling, comprising:
a cup having first end portion defining a through opening and a cylindrical body portion connected to and extending axially from the first end portion to a second end, the first end portion and the cylindrical body portion defining a through-opening axially through the first end portion and the cylindrical body portion, the through-opening having a cross-sectional shape of a circular region intersecting an elongated slot, the cup further defining a recess extending axially part way into the cylindrical body portion from the second end, the recess having a slot shape oriented transversely to the elongated slot of the through-opening;
a post extending axially between a first end portion and a second end, the first end portion of the post having a protrusion extending laterally outward, wherein the post is configured to pass through the through-opening when the post is in an unlocked position and the protrusion is configured to be received in the recess when the post is in a locked position;
an attachment point connected to the second end of the post;
a spring on the post between the attachment point and the cup; and
a receptacle secured to the handguard, the receptacle defining a threaded opening configured to threadingly engage the cylindrical body portion of the cup.
12 . The handguard of claim 11 , wherein the attachment point comprises a D-ring pivotably attached to the second end of the post.
13 . The handguard of claim 11 , wherein the first end portion of the post defines a T-shape.
14 . The handguard of claim 13 , wherein a combination of the slot of the through-opening and the recess define a plus shape as viewed looking axially into the cylindrical body.
15 . The handguard of claim 11 , wherein the post defines a threaded bore extending into the second end and the attachment point includes a threaded rod, and wherein the attachment point can be secured to the post by threaded engagement between the threaded rod and the threaded bore.
16 . The handguard of claim 11 , wherein the second end of the cylindrical body is open.
17 . An adjustable stock for a long gun, comprising:
a quick disconnect assembly for a sling, comprising:
a cup having first end portion defining a through opening and a cylindrical body portion connected to and extending axially from the first end portion to an open second end, the first end portion and the cylindrical body portion defining a non-circular through-opening, and the cylindrical body portion defining a recess extending axially part way into the cylindrical body portion from the open second end, wherein the cylindrical body portion is threaded;
a post extending axially between a first end portion and a second end, the first end portion of the post having one or more protrusions, wherein the first end portion of the post is configured to pass through the non-circular through-opening in the cup when the post is in a first rotational position and wherein the one or more protrusions are configured to be received in the recess when the post is in a second rotational position;
