I'm having a hard time deciding on this one.
I would go this route but I already have an 762 SDN-6. So, I was thinking dedicated 5.56/.223 can.If I were a F4 buyer I'd get the Saker 7.62 and never look back. Actually quieter than the 5.56, with the 5.56 end cap, and MUCH more versatile. YMMV. As noted above the Saker mounts are much better than the AAC 51T.
This is what I say all the time. In the end unless you have shot a lot of different silencers then you won't be disappointed. If you have shot several different ones then you already know what you like.That said - suppressor technology is like computer technology - you may get the latest and greatest - but sure enough as soon as you get your tax stamp.... there is something better
