As the title alludes to, I have an M4gery and will be putting together another AR chambered in .22 - I want to get a can that I can use on both rifles but I don't know if there is anything I need to be aware of and what would be some good recommendations for this dual application.  What do you think?

A .22LR suppressor will not work with .223 but a .223 suppressor will work with both.  You'll hear people talk about the .22 leaving large amounts of debris behind which will eventually lead to decreased performance.

The Tac16 is a take apart .223 can.

I think it is a bad idea... just get a dedicated .22 can.  I too wish it was possible to shoot both without incident but it's not.

Even with jacketed bullets?

I have a TAC-16. While it will work with .22, it is far from ideal. On an AR with a .22 conversion, it's not too bad. On a .22 rifle or handgun, it's excessively heavy.

The only time i use my TAC-16 for .22LR is for full auto .22

I don't think it's so much a bullet issue as it is a pressure issue.  Too much pressure in a .223 for a suppressor designed for .22lr to handle.

Not telling you to do it/not dot do it, but a friend of mine has an older Gemtech M4-96D QD 5.56 can that he has shot 1000's of 5.56mm & 22LR, mostly full-auto, w/o any problems. He uses it on a M16 with a 14.5" 5.56mm upper and a 5.5" 22LR upper.

It's heavy, but it still sounds pretty decent.

I have a Sound Tech .223 suppresor.  It shoots great on my AR, my 10/22 and and a cheap .22 bolt rifle I had the barrel threaded.  No issues no worries.  I bought the .223 can with the intension of shooting both.  IMO the .22 is quieter with my .223 can than with a .22 can.  My guess is the larger volume.  Truthfuly I couldn't tell you the reason.  

There is no question that the .223 can is heaver than a .22 can.  But the ability to shoot it on an AR makes up for that difference.  Keep in mind that both are .22 cal bullets.  Both are sub sonic.  If both are .22 cal and both are traveling at 1,050 fps, then one is just more expensive to shoot (.223) than the other (.22).   But you can count out the cool () factor of shooting a can on the AR.

Thanks for the replies.  It seems that the safest bet is to get a dedicated .22 suppressor.  From what I gather, shooting .22 through a can will dirty it up rather quickly, right?  In that case I'm guessing that a non sealed can is preferred for the ability to clean it?  Am I on track?  What are some of the better suppressors out there that are reasonably priced?  I'm not made of money but I also don't want a piece of shit.

ummmmmm.......really????.....ok

Even a non-sealed can will tend to 'weld shut' from excessive .22LR use.  

I use a 9mm/.308 can with my 22LR uppers at times.  When I switch back to FA use the carbon/lead deposits tend to break loose.

On my dedicated 22LR can, it is slowly filling up with carbon and lead.

Not sure how I am going to clean it, because it has fused shut.

I suppose I'll take this one.

.223 is NOT subsonic.  Just because both bullets measure .22" in diameter DOES NOT mean they travel at the same velocity

.223 = 3000fps give or take

And many .22LR can travel at supersonic speeds, given enough powder and enough barrel length.

Surprises me that someone who allegedly owns a suppressor would know this little.

BTW: as others have said, interchanging between the two without cleaning out .22LR debris is a bad idea.
