    I have neither rifle and want a suppressed one. So if you could afford only one --suppressed .223( AR) or .308 (HK91) which would it be and why?

    Though I would opt for a gas operated rifle like the FAL, with an adjustable gas system.

    I wish I had either option, but personally I would probably go with a .223

    Im not going to lie, but I have very little knowledge on suppressors and their effects on different calibers, so I have to ask the question. Is .223 quieter than .308 when used with a suppressor?

    Sorry to drift, but do you have a suppressed .22LR rifle?

    No, I don't have anything chambered in .22LR. Brentn, I wanna say .223 is all around quieter suppressed, but I'm not sure.

    Unless your using sub sonic loads your still going to hear the crack of the bullet.

    and it's hard to get a .223 subsonic stabilized in a 1/9 barrel, like in most AR...

    I tried it in my M4 with supressor, using 80grains molycoated bullets and shooting rounds 1 by 1, since it would not cycle the bolt... but frankly the sounds suppression is not worth it (mostly because .223 supressor are made to suppress supersonic gaz expansion, and you will still hear the supersonic crack, but you shot will be very hard to localize) compared to a standard 22lr ammo supressed in a bolt rifle or semi auto, which make NO more noise when shooting than a airgun (pellet gun).

    you could stabilize a subsonic 55 grain bullet in an 1/9 barelled AR, but than, the ballistic efficency of this bullet would be exactly the same as a 22lr, and it would still make more noise..

    If you want something really stealthy, go for a good 22lr supressed.

    Now, I heard about 300 whisper etc, but never tried it. maybe it's the best way, if you can afford it. Here, there's no such way.

    btw, obviously the .223 would make less noise than the 308 with a same technology suppressor... and this is due to the volume of expanded gaz (more in a 308, so harder to supress)

    I believe the argument goes that for optimal suppression, since you need to slow down bullets to below the speed of sound anyway, bullets that rely more on mass than speed (as in 7.62 compared to 5.56) will lose comparatively less energy.

    a subsonic 7.62, in my mind would have a terrible dropdown, and therefore a very poor ballistic.

    suppressors on assault rifle, are not meant to make the gun silenced, but to make it very hard to localize you when you are shooting with.

    Gemtech makes a suppresor for the 223 that is an "entry supprosor" It just quiets the gun enough that it doesn't ruin your hearing as you shoot indoors. You can thread this on a 22lr but it still doesn't hide the sound barrier pop.

    Just a suggestion here...

    Why .223 or .308? If you want a suppressor, go WAY silent... Get a .45ACP bolt rifle with an integral can, like the new copies they're doing of the delisle...

    No, it is not a thousand yard rifle. But if you have your bullet drop stuff together, and know how it is going to shoot, it's a 200 yard rifle.

    Take your question over to www.SilencerTalk.com

    Good guys, lots of knowledge--that is how I made the decision on mine.

    What is the overall goal you are trying to meet here?

    I've fired my 16" AR with an OPS Inc. 16th model next to a .308 AI with a Jet can and the AI was noticeably quieter. So caliber isn't the only issue.

    I think you'll have a hard time getting the HK91 quieter than an AR though and man, it is going to be filthy.

    suppressed or unsuppressed, i'd take an AR over an HK91 any day, for nearly any purpose.

    my goals in suppressing a rifle, in order of importance:
    1. ear pro
    2. they're kind of cool / conversation piece
    3. possession annoys liberals / gov doesn't want me to have

    note that none of those involve hollywood fantasies

    Maybe with two of us asking, there will be an answer to this question. I really don't understand the desire regarding these two rounds.

    The best thing to do is find a round that can go subsonic and still be effective, then go from there.

    .223 is harder to do subsonic, build an ar in that 338 whisper or whatever.
  18. Vegaslaith

    Vegaslaith Well-Known Member

    The overall goal is to have a suppressed rifle that is quiet and doesn't drop as much over a long distance. I don't know too much about ballistics though, just that gravity eventually overcomes a bullet's trajectory.

    then the whisper is for you, look it up, it's a really interesting round

    More on the 338 Whisper.


    300 grain or up if you can find the bullet or make it (cast) seems to be a good one, but if you want less drop and less FPE then lighter is better.
