7. AUTOMATIC FIREARMS: e.g. ASSAULT RIFLES, (SUB)MACHINE GUNS, AUTOMATIC PISTOLS

7.1 Barrel: Cut a longitudinal slot through the barrel including the chamber where present (width: > calibre; length: for rifled barrels three times the length of chamber and for smoothbore barrels twice the length of the chamber).

7.2 Barrel: A hole must be drilled across the chamber through both walls and through which a hardened steel pin must be inserted and securely welded (diameter > 50 % chamber, min 4,5 mm). The same pin can be used to secure the barrel to the action. Alternatively, a plug of the size of the cartridge case must be inserted into the chamber and securely welded.

7.3 Barrel: Remove the feed ramp where present.

7.4 Barrel: The barrel must be permanently secured to the firearm by welding, bonding or by using appropriate measures with the equivalent degree of permanence. The pin used in operation 7.2 can be used for this purpose.

7.5 Barrel: For exchange barrels not affixed to the firearm, apply operations 7.1-7.3 as applicable. In addition, the barrels must be permanently prevented from being affixed to a firearm by cutting, welding, bonding or using appropriate measures with the equivalent degree of permanence.

7.6 Breech block/bolt head: Remove or shorten firing pin.

7.7 Breech block/bolt head: Machine or remove the breech face at an angle of between 45 and 75 degrees as measured from the angle of the original face. Material must be removed across the entire breech face. All locking lugs must be removed or substantially weakened.

7.8 Breech block/bolt head: Weld the firing pin hole.

7.9 Slide (for automatic pistols): Machine or remove the breech face at an angle of between 45 and 75 degrees as measured from the angle of the original face. Material must be removed across the entire surface.

7.10 Slide (for automatic pistols): Remove the firing pin.

7.11 Slide (for automatic pistols): Remove locking lugs in slide.

7.12 Slide (for automatic pistols): Where applicable, machine the inside of the locking edge of the ejection port in the slide to an angle at a range of 45 to 75 degrees.

7.13 Slide (for automatic pistols): If the breech block can be taken off the slide body, the deactivated breech block has to be permanently fixed to the slide body.

7.14 Frame/Receiver (for automatic pistols): Remove feed ramp where present.

7.15 Frame/Receiver (for automatic pistols): Machine away at least 2/3 of the slide rails on both sides of the frame.

7.16 Trigger mechanism: Ensure destruction of the physical operating link between the trigger blade and the hammer, striker or sear. Fuse the trigger mechanism together with weld within receiver/frame, where applicable. If such fusion of the trigger mechanism is not possible, remove the trigger mechanism and fill the area with weld or epoxy resin.

7.17 Trigger mechanism: The trigger mechanism and/or housing has to be welded to the receiver/frame (in case of steel frame) or glued to the receiver/frame with high temperature resistant glue (in case of light metal or polymer frame).

7.18 Automatic system: Destroy the gas piston, gas pipe and gas port by cutting or welding.

7.19 Automatic system: If there is no gas piston, remove gas pipe. If the barrel is used as a gas piston, weld the deactivated barrel to the housing. In all cases where present, close the barrel's gas vent by welding.

7.20 Automatic system: Machine or remove the breech face at an angle of between 45 and 75 degrees as measured from the angle of the original face. Material must be removed across the entire surface of the breech face and elsewhere so that bolt/breech block is reduced by minimum 50 % of original mass. Permanently fix the breech block to the firearm by welding; bonding or by using appropriate measures with the equivalent degree of permanence.

7.21 Automatic system: In cases where bolt heads are incorporated into a bolt carrier, the carrier must be reduced by a minimum of 50 %. The bolt head must be permanently fixed to the carrier and the carrier must be permanently fixed to the firearm by welding, bonding or by using appropriate measures with the equivalent degree of permanence.

7.22 Magazines: Weld the magazine with spots or use appropriate measures with the equivalent degree of permanence, depending on type of arm and material to prevent removing the magazine.

7.23 Magazines: If the magazine is missing, place spots of weld or use appropriate measures in the magazine location or fix a lock to permanently prevent the insertion of a magazine.

7.24 Magazines: For tube magazines, drive one or several hardened steel pin(s) through magazine, chamber and frame connecting them permanently to each other. Secure by welding.

7.25 Silencer/Suppressor: Permanently prevent removal of the silencer/suppressor from the barrel by use of hardened steel pin or by welding, bonding or by using appropriate measures with the equivalent degree of permanence, if the silencer/suppressor is part of the weapon.
