This serves the same purpose as the Spacer Eraser Milspec Hammer Jig included in my Lee Sporting Supporting Pack except this is for the Geissele SSA-E when used with the Lee Sporting. Using this will allow the recoil buffer spacer to be eliminated when using a full size/reverse stretch MP5. Files includes a clip-on attachment that clips over the hammer, lol and 2 jigs to reprofile the hammer. Use jigs in numbered order. Only confirmed to work with the Lee Sporting + Geissele SSA-E, not sure yet whether it will work with other lowers or Geissele triggers/hammers. Clip-on attachment originally designed by @S3igu2:c.
