Re: Question for current owners - regrets?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Strykervet</div><div class="ubbcode-body">I wish I had known the SDN6 didn't fit tight on all the mounts (it fits each one differently! from snug to rattle!), and that AAC was going to bitch about it and say "that is normal" when I know damn well it isn't supposed to jiggle. And that 3mo. after I bought it, they'd come out with the new generation! 51T mounts --only way to make 'em work is to lap is the mating surface of the mount, which of course destroys the warranty. AAC replaced the 51T with a new, non-backwards compatible 90T ratchet. Not sure how well it works, but I suspect it is almost twice as tight? Or rather, 2x less jiggle?
I don't know how other QD's stack up.
I can say the SDN6 is impressive for its size, it is quieter (firing 5.56 or .300 supers) than two, longer, different pistol suppressors I saw at the range one day, a .45 and a 9mm, one an AAC or AWC and one a Gemini. That came as a big shock, I didn't expect movie quiet, but with new suppressors that long and the .45 firing subs, I did expect more. I won't be buying any pistol suppressors, as long and unwieldy as they make the pistol vs. the meager permormance, save an integral Ruger Mk2 (I hear Mk3's are worse for conversion to integral for a variety of reasons) which is the absolute most quiet pistol I've ever heard or shot. It was an S&H in the mid-late 90's. Sure they are even better now. Those ARE movie quiet, if not moreso. Their integral .45 and 9mm camp rifles are very quiet too.
But after I get the other mounts fixed, I'll stick with dedicated, thread on or integral suppressors for the rest of my gear. Besides, the SDN6 covered 5 rifles in four calibers, 5.56, 6.5G, .300BLK and 7.62. That's a plus. Kind of expensive to turn back now, cheaper to lap the mounts and suck it up, and now the Grendel, it fits real tight. They aren't off much, but it is enough to be a problem, enough to be fixed.
For any subsequent rifles, save one 7.62 I have a mount for, they'll all get thread on. And anything I expect excellent accuracy from, it'll get a thread on. Accuracy does suffer when the suppressor jiggles in ANY direction.
I also do like the materials AAC uses --Inconel blast baffles and the high end, high performance stainless steels. So that is a plus. With the .338 or .50 or whatever biggie I get, I'll go with titanium and Inconel though, as they won't see as much firing per session.
Just my .02 and what I've noticed and plan to do. </div></div>
Stryker, I had the same issue as you with 2 of my four mounts. What I did was put 3-4 rounds through the suppressor, just enough to get it warm. I was then able to get it to latch on that last tooth with no wiggle. After doing this 3 or 4 times, the suppressor locks up tight on all 4 mounts when cold with no extra effort.
