In my experience, its hard to be disappointed with any can...but you get unreliable advice from people that have only heard or used one or maybe even two models.
A family member is a dealer so I get to test out just about ANYTHING I want.
I know that I chose my first can with to much emphasis on the low price point.
I now know better.
This is a lifelong investment. You can always ditch a scope or gun...or trade off a product that you bought pinching pennies...with intentions of upgrading later...but with a can...there is almost zero resale value. It will likely be with you A LONG TIME. If there was ever a time to "Buy once and cry once" its with a suppressor. Set asside $50 or 100 a month and research as much as you can. By the time your actually ready...you'll have the extra built up for something better.
Knowing what I know now...I would sell a gun to buy a better suppressor. No question.
my first was a YHM SS Phantom QD.
It's an EXCELLENT suppressor and even in the upper end of sound suppression, but its.crazy heavy.
I've since bought a second .30 cal can in titanium. (Thunderbeast 30BA) It's hard to justify DOUBLE the price for reduced weight, but there are models that are very competitive.
The YHM 5.56 Phantom Ti model comes to mind. Proven suppression, light weight and great price point.
The absolute best 5.56 can I have heard is the SRT Hurricane XL Ti. It's almost impossible to tell the difference between 1-2 dB with the human ear, but with this can...its easy to hear the diff. Another thing that isnt usually mentioned is that some cans that have a thin tube to reduce weight, will have a noticable "ping" sound...like a tuning fork when you shoot. I've heard an AAC Cyclone do this.
Different models, designs, materials simply have a different tone when shot through them.
Majority of suppressors have a repeatable point of impact, but they don't always have a consistent first round impact. Some Gemtech cans have this issue.
Another important feature is that some cans will improve accuracy (a lot or a little) and some will degrade accuracy (a lot or a little)
A few like SRT and Thunderbeast have proven to usually, improve a rifles accuracy.
I could go on and on and on, but the questions about the Tac-16...I'm afraid I'm no help.
