Thanks for the reply.....what I infer from your post is that, with the described DTA system, one is still "stacking tolerances" but since the parts were engineered to work with each other the tolerances are minimized (tighter) and their sum, being smaller than the sum of the tolerances in a system where the parts art not engineered to work specifically with one another, does not have as detrimental effect on accuracy. Makes sense....
Just to be the devil's advocate.....Taking the effect that any particular suppressor's baffle stack has on bullet flight out of the equation and just looking at tolerance stacking.....if one had a great machinist who could fabricate an adapter that would minimize the tolerances (between the adapter and the barrel as well as between the adapter and the suppressor....maybe even mimicking the tolerances of the DTA system) the same results could be achieved.
To concisely insert this thinking into your lens analogy....if the original lens was replaced with a lens of equal or better quality your may retain the same image sharpness or even achieve a sharper one....
I could be totally off base if I'm not understanding the concept of tolerance stacking...I am by no means an engineer.
I too am am planning on getting a DTA can. From what I've read they sound amazing.... short, light, and rated for .300WM in the .30 cal version (my current cans are not and I am planning on getting a .300wm conversion in the future, will most likely never go .338). Not to mention their looks are waaaay cool. I inquired with DTA and was told the wait would be waaaay long (not including ATF wait time) and in the interim I'm going to want to do some shootin' and I don't think I want to shoot that covert a whole lot without a can on it....lol...so an adapter is in my future.
I am very excited about the accuracy potential in this system, as well as it's compactness. I've never even seen one in person. I can't wait to get my hands on mine...

A long wait would be an understatement. I ordered the 338 titanium in Feb and was told a year til its manufactured, and this was before the A1 craze. I have no interest in shooting my DTA subsonicly so I am not worried about The long wait. The main purpose for me is squeezing the last bit of accuracy out of my rifle as well as making my Covert not look so weird with a BEAST on top of it. Plus I paid like $400 for the Covert soft case so I may as well utilize all the pockets.
