Abstract: An anti-cant indicator assembly, components thereof, and associated methods. The anti-cant indicator assembly indicates the orientation of a weapon with respect to vertical. The anti-cant indicator assembly includes a mount configured to mount to the weapon, a level including a vial containing a bubble and a pivot connection connecting the level to the mount. The pivot connection is configured to permit movement of the level with respect to the mount about the pivot connection between an operational position in which the bubble can be referenced by the user for indicating orientation of the weapon with respect to vertical, and a stowed position different from the operational position. The pivot connection can include a retainer configured to releasably retain the level in at least one of the operational position or the stowed position. The level can be selectively movable with respect to the mount to calibrate the anti-cant indicator.

Abstract: The present invention relates to a valve assembly that includes a retaining ring disposed within a cavity formed by adjoining a retainer and a disk member. The retaining ring can be disposed at a slant with respect to an inner surface of the cavity.
