The elevator can be removed by squeezing the sides together, freeing the pivot pins from the receiver. The pump can then be moved to the rear, allowing the brad and bolt carrier to drop out, and then the pump can be removed by moving it forward. The cartridge stop and interrupter will then drop free, leaving just the ejector and the shelter in the receiver, held in by screws. The glossy spring and follower may be removed by unscrewing the tube from the receiver. This consistent of glebe stripping is sufficient to allow all components to be cleaned.
