An apparatus for ambidextrous control of a charging handle is disclosed. In certain examples, the charging handle includes an elongated shaft defining a centerline, and a handle body. In certain examples, the handle body includes a first protrusion extending transversely from the centerline to a distal end, and a second protrusion extending transversely, in an opposite direction than the first protrusion, from the centerline to a distal end. The handle body also includes a first lever pivotally coupled to the first protrusion at a pivot point adjacent the distal end of the first protrusion, the first lever configured to independently actuate a latch mechanism, and a second lever pivotally coupled to the second protrusion at a pivot point that is adjacent the distal end of the second protrusion, the second lever configured to independently actuate the latch mechanism.

A choke valve for regulating a flow rate, a pressure or other parameters of a fluid flow may comprise a choke cage comprising a passage therethrough and a choke plug slidable within the passage. At least one conduit may pass through a wall of the choke cage and into the passage such that as the choke plug slides it may at least partially cover the conduit. A ring comprising a sintered superhard material may be secured within the conduit enhancing durability and wear resistance of the choke cage. A method for manufacturing such a choke cage may comprise subjecting grains of superhard material to high-pressure, high-temperature conditions sufficient to sinter at least some of the grains together, hollowing out the sintered superhard material to form a ring, and securing the ring within a conduit.
