Breech Bolt assembly and slide assembly will be cleaned with appropriate solvent and a light coat of lubricant will be placed on these parts. C. Receiver can be brushed out but will not be submerged in the cleaning tank. If it needs to be detail stripped, an agency armorer shall clean this part. 4. Shotgun Reassemble After all above parts have been cleaned and lubricated, the weapon will be assembled in reverse order as disassembly. A. Hold receiver in hand. Place Fore-end assembly on magazine tube. Place breech bolt assembly and slide assembly on the slots located on the Fore- end rails. Push the Fore -end assembly into receiver by pushing in on the slide latches located on the underside of the receiver. The right shell latch needs to be pressed in first as the Fore -end assembly is moved slightly to the rear about ¼ of an inch. Then press the left shell latch to allow the assembly to move into its proper place. B. After Fore-end assembly is in place, press the action bar release and pull the Fore-end assembly half way to the rear. This will allow the barrel to be properly p laced on the receiver . Confirm the barrel ejector base cut out is properly placed around the ejector base. If this is not done, the ejector base will be damaged and the shotgun will have to be taken out of service. Then replace the magazine cap. The ca p should be finger tight. C. A function test will be performed after reassembling, i.e.; confirm the weapon is unloaded, point the weapon in a safe direction, work the Fore -end to the forward position, pull the trigger and listen for the hammer to fall, k eep the trigger to the rear as you work the Fore-end again. Then slowly release the trigger and you should feel and hear the sear reset. Place the weapon on safe and there should be no movement in the trigger . (A light coat of oil will be applied to the surface of the weapon.)
