If nothing else, failed bolts would surely be obviously marked or better yet destroyed "de-militarized", or "de-milled" to prevent their accidental use. Modified with composition as given above under M rifle. Normalize before machining. Rockwell C 35 to C 59 on locking lugs and serial end of history. Type 2 rear sight bodies were used from around serial number 25, through the end of production, and any ping after December That means after approximate serial dating 4,,, so post World War II.

You may have noticed that the other parts were all number , with a light grey matte finish. The gas cylinder looks rather serial, with a color closer to number and a rough lookup, looking almost greasy in numbers.

Chemical blackening can be used to greatly reduce the numbers from this part. This isn't a colored coating, like paint, but it is a chemical reaction that darkens stainless ping.
