    I'm curious about noise suppressors (silencers). Mostly, I think it would be cool to have one. I have a lot of questions about them though.

    1) Is a suppressor gun-specific? Or caliber specific? Rifle vs. pistol specific? You get my drift.

    2) Is the tax stamp per suppressor?

    3) Is the tax stamp person-specific? If my wife got one, would I be able to shoot it and if so under what conditions? Could we let someone else shoot it?

    4) Does a gun need to be modified to use the suppressor?

    5) How heavy are they?

    6) How hard are they to remove? Do they really just screw on like in the movies?

    7) How much do they affect the trajectory or velocity of a bullet?

    OK, that's it for now. Thanks!

    1. Supressors are caliber specific. Sometimes different barrels have different threads and adapters are available

    2. Yes. One $200 tax/device

    3. If it is "registered" to an individual, that person must be present. Some are registered to a "trust", anyone listed on the trust can be in possession of the device

    4. A gas operated gun may need some degree of modification. An AR will probably need a very heavy buffer (H-3 or 9mm)

    5. Maybe a pound or so

    6. Most are threaded and just screw on.

    7. They will affect the trajectory to some degree. Each gun/suppressor combination will be unique

    The Feds make is as difficult as possible to own a suppressor.
    Your state must allow them as well.
    Your Chief Law Enforcement Officer must be willing to sign the forms. Trusts bypass this requirement but our Prez is changing that.
    Quality suppressors are not cheap. Cheap suppressors are not quality.
    The current wait for the BATFE to approve an individual transfer is at or over one year. It is several months wait to approve a transfer from one dealer to another.
    So if you can get your sheriff to sign off, if your state allows it, if you have the funds for the tax and a decent suppressor and if you can wait at least a year, suppressors are crazy awesome and I highly recommend them.
    Go to the silencer forums on another site and read up on everything.

    This sums it up nicely. Be aware of the downsides. A mounted suppressor will shift the weight balance forward. It will cause more chamber fouling and sometimes a powder gas blowback in your face. It may cause malfunctions due to increased chamber pressures and altered cycling. Not every firearm likes to be suppressed, so choose your suppressor host wisely.

    i own two.

    bolt actions make the best suppressed rifles. direct blowback pistols make the best suppressed pistols. it helps to use subsonic ammo but testing MUST be done to ensure any radically different ammo than the norm does not key hole. baffle strikes can ensue blowing up your pricey toy.

    in general a suppressor for a larger caliber can be used on a smaller. i use my .308 suppressor on my ar15 which is 5.56/.223 and it works better than a supressor design for the 223/556 due to the larger volume of the suppressor.

    suppressors do not affect max range or velocity of the round, as is so often depicted by bad video games, but do increase back pressure so book max loads should never be used with one.

    the supressor either needs an adaptor for QD models to swap from gun to gun or the gun must be threaded with the same thread pattern if its a screw on type.

    Why are they awesome? And why do you recommend them?

    They are awesome because form what i understand, in most cases, they negate the need for hearing protection. And they serve as a flash suppressor, too. I have shot a suppressed 10/22, and most of the noise was from the action racking back and forth.

    Where to begin.... I got my first can because I wanted to see what they could do. Then I needed a rimfire can and now I'm waiting for a rifle can.... Maybe I'll stop there.

    First, it greatly reduces muzzle blast. It is safer for you and others shooting around you if at a range. Ever felt the heat and pressure wave from the 300 win mag next to you?
    It reduces the muzzle blast signature. Hearing protection for you and fellow hunters/shooters. Supersonic rounds are tolerable without hearing protection but not truly hearing safe. Subsonic rounds range from hearing safe to nearly silent.
    It hides the location of the shooter. This may sound like a combat/assassin type thing but is critical for hunters. The prey will not hear or cannot tell the location of the gunfire which often confuses them and they are less likely to scatter. That can be very helpful if one misses or is hunting multiple hogs/coyotes etc.
    I can load a round and walk into my back yard and test the round without my neighbors being disturbed. It is a lot more handy than driving all the way to the range to test loads.
    Yard vermin can be dispatched without any neighbors being disturbed, especially anti gun cop calling neighbors.
    For home defense, it protects hearing for everyone so verbal communication is easier. It also protects low light vision by nearly eliminating the flash.

    Some things won't happen. Guns are never truly silent. Supersonic rounds are still loud due to the sonic boom. The gun will be somewhat harder to hold and aim with a weight on the end of a barrel.

    Ever see Zero Dark Thirty? It shows the SEALS using AAC SDN cans. Yet in one scene it shows the outside of the building while inside the SEALS are popping a few rounds to make sure the bad guys are dead. The movie shows bright flashes coming out the window. That is all Hollywood magic as the flashes would be virtually non existent with a can

    Those are good reasons. Especially the home defense example.

    I really want one for my P22. It would be awesome for getting rid of the possums and coons that find their way under my deck and into my garbage.

    Never thought about registering it to a trust though. I may look into that. Still a hefty price tag once you factor in the demand and tax stamp.

    Do they have a life expectancy?

    I have a P22 and a Sparrow. Sparrows are not as efficient on pistols so if you primarily want it on a pistol, get a Spectre II. My local dealer had them for $350 and then add the $200 tax stamp. Submitting E-forms can speed up the process. I used a trust that I drafted myself. If I get another NFA item and if the BATFE wants prints and pictures of all names on the trust, I will go the individual route. I have a new sheriff and he is a Democrat so I don't know if he will sign. I can't print 8 people, especially a minor who is a beneficiary.

    Most will last longer than you will. Baffle strikes are one way to seriously damage a suppressor.

    Most 22 long rifle cans will come apart for cleaning.

    Cheap cans are cheap. $200 will get an aluminum 22 can that won't disassemble. Don't buy cheap cans! $350 will get a stainless steel take apart rimfire can that will last a lifetime.

    Was spot on with his comment that a larger caliber suppressor works on a smaller caliber rifle. For example in testing suppressors last year we found that the 308 suppressor on the 223/5.56 AR Rifles was quieter than the 223/5.56 Suppressor for the rifle. So if an when, I get one it will be for the 308!

    The thread pitch is different. But you can find an adapter.

    yes but i doubt you will ever buy the hundred thousand or so rounds to wear one out. you will go through several guns before the suppressor dies.

    depends. i use qd suppressors for centerfire. screw on ones are far too limiting in what you can use em on. if your going to go through the hassle of nfa just get a damn good adaptable to many guns suppressors. my surefire fa762k goes from the wife's 308 savage 10fcpsr to my scar17 and also mine and her bcm carbines... all have different thread pitches.

    if you have a screw on type you cant use it on a 308 ar10 if you bought it to fit your m1a... no adapters to do that

    I'm waiting on the ATF for a Gemtech 22 supressor. Everything paid for and in the mail about three months ago. My threaded 4.5" Ruger MK3 22/45 is anxiously awaiting it.

    Next up will be a 7.62 can...to be used for 308, 300blk, 5.56. Looks like that'll be a pretty spendy process, and may require an additional tax stamp (300blk SBR) as well.
