Anyone played with barrel length and suppressors?

[fixin]

Would the -L series help?
I'm thinking of my 12.7 barrel build and wondering what the Deadair Sandman suppressors can actually do. I'm just getting in to this game, so any input would be appreciated.

I suggest doing all of the research you possibly can and take a deep look at what you want the gun to do. Definitely don't settle... if you are looking for a light weight build then a titanium suppressor will be the better option, if you want a little bit of weight then you can't go wrong with alloy. One last tidbit... there is no set standard for suppressor testing. Military do their tests one way, a company does it their own way and another company does it even differently, so just because a company advertises a particular decibel rating doesn't necessarily mean it will work for your application. I have a Q LLC trash panda sitting in jail currently, I picked it for the weight, construction, price and mounting option and ignored the decibel rating since I don't have any first hand accounts/experience for the sound reduction.
