How do you evaluate how good a can is? Do different cans excel in different areas? What kind of life can you expect out of a can?


I'm no scientist when it comes to evaluating suppressor noise, so I'll leave that to the other folks.

However, I have an old(er) model M4-2000 and when I shoot at our club Practical Rifle matches, the guys in my squad take their hearing protection off and speak normally. The YHM may be machine measureably quieter, but whether your ears can tell the difference is another matter.

I would say, go on the features you like. Mine is QD, but honestly, I never take the suppressor off except when I clean the barrel.

The other thing you should be aware of is that suppressors get hot fast. I almost melted my way through a very nice case after a long string (we have to bag our rifles before the next shooter can come up).

A well built hot suppressor isn't going to look any different from a cold one (unless you have a sear, you're unlikely to get to glowing hot temps). Bring along a spray bottle. If you spray the suppressor and barrel and the water boils on contact, it's not safe to put away, set it out, lock the bolt back and let it cool. It's a cheap and easy way to keep from bbq'ing your mits.

Now THAT is a good tip!! LOL I didn't realize they got uberhot!!

One thing I noticed.....some suppressors screw into the barrel in lieu of a flash suppressor. Is there any pros or cons to that?

Having dealt with AAC over the years, I have not had any problems.

Every company will have a few detractors over the years. The top 5 or 6 companies all make great cans.

Try to hear the can in your setup, before buying one. This allows you to see/feel/touch it.

Most humans can only hear a change in sound energy roughly around ~5db difference. Every 3 db is a doubling or halving of sound energy.

Two cans which have a 2-4 db sound energy difference will likely not be noticeable by shooters and for some of us maybe even more than 5 or 6db ;-(.

I tend to not take a can off of a rifle unless cleaning it. The bi/tri-lock technology is less useful to me and I *personally* do not buy it any more. Again, that is my experience. You have to choose what is right for you. If the fun factor is worth it, then get a can with the *-lock technology.

You can also get a feel for value by taking the cost and dividing the db reduction to reach the cost per db reduction. This is a *ball park* figure to see what you are willing to spend.

Have fun.

When you consider that the decibel is a logarithmic measurement it can indeed be a big difference.

Just in case you missed it.

From my original post:
"Every 3 db is a doubling or halving of sound energy."
