- This was discussed on rec.guns a while back, and a FAQ is in the
- works. Hopefully the moderator will cross-post when it is on-line. In
- any event, the only .223 I've seen with silencers weren't particularly
- silent, Sarah Connor in Terminator 2 notwithstanding.

- However, one selling point of the HAC-7, made by Holloway
- Arms Corporation as a battle rifle (I hate to say 'salt weapon), was
- an adjustable gas regulator. It was chambered in 7.62 NATO, and was
- capable of being silenced. There were five positions on the gas
- regulator, the first four being for heavy-to-light ammunition, and the
- last being no gas at all. This last setting was to be used with
- subsonic ammunition and silencer, and kept the bolt from opening at
- all in order to reduce noise. Is this even made today? I read about
- it at least five years ago.
-
- I'd suggest that an M-16 could fire suppressed, but you would
- need to adjust the gas regulator to cycle the action, or just cycle
- it by hand after each shot.
-
- Additionally, silencers work like glasspack mufflers on cars.
- The silencer absorbs the heat and blast from the muzzle. It does not
- slow the bullet. Those that might must be an integral part of the
- barrel (holes drilled in it?) else your accurracy is killed along with
- the sound. A supersonic bullet and a silencer are, at best, going to
- silence the initial report, and is hence somewhat less than ideal.
