A firearm slide accessory includes a charging handle attachment that includes a base member and a pulling member that extends from the base member. The pulling member includes a pair of side members that extend from the base member and which join to form a cross member parallel to the base member. The side members and the cross member define an opening through which sights of a firearm are viewable.

A weapon is capable of firing cased telescoped (CT) ammunition rounds. The weapon includes a barrel, a chamber member that defines a chamber configured to hold a CT round for firing from the weapon, a non-rotating carrier body, and linkage. The linkage is constructed and arranged to move the chamber member (i) from a firing position in which the chamber member is aligned with the barrel for firing the CT round to an ejection/loading position in which the chamber member is not aligned with the barrel for ejecting a spent CT round and receiving a next CT round in response to the non-rotating carrier body moving away from the barrel, and (ii) from the ejection/loading position to the firing position in response to the non-rotating carrier body moving toward the barrel.
