Re: 7.62 or .338 Supressor?
I have a Ti SAS QD 338 can that I use on my DTA in 338 LM, 308, and 6.5 CM. I also use it on a 9" 300 AAC BLK.
As far as sound goes, I have never shot with a can that sounded quieter, and have shot with a lot that have sounded much louder. This goes for all 4 calibers.
For accuracy, it actually increases accuracy on the 338 by about .15 MOA. The 308, both supersonic and subsonic, and 300 AAC the can has no effect on accuracy. With the 6.5 it seems to spread it out a bit. I'm talking about .1 MOA. However, friends of mine have cans of different sizes and manufactures, and that seems to be a trend with the 6.5 CM with a suppressor. Dunno why.
For the muzzle break itself, the QD is good, but not great. My brother in law owns the thread over muzzle break version for a 30 cal can. That break is as good of a muzzle break as I have ever shot with can attachment or not. If I were to do it over again it would be a thread over muzzle break.
For price, there is no comparison. SAS Titanium cans rule.
