Looking for a suppressor to use on my ARs as well as my hunting guns... mostly .243 and 7mm Rem Mag.

Local dealer carries:
Specwar 7.62 QD
AAC Cyclone, SR7, SDN-6, etc... pretty much all the AAC offerings.

If I can use the suppressor on the 7mm, that would be GREAT... if not, it's not necessarily a deal breaker but I'll probably buy a .308 down the road.

What's your recommendation with regards to effectiveness, accuracy, etc.?

AAC MK13 SD, TBAC 30BA, Gemtech Quicksand  

I would look for something light that has a qd mount to accommodate the different threads.

Suppressed Armament Systems sells magnum rated cans at a reasonable price.  Look at the Reaper and Arbiter.

As mentioned, Thunderbeast sells them too.  TBAC seems a bit more popular than SAS from my reading.

I'm just about to pull the trigger on a slightly customized Reaper.  The 10 oz weight is crazy.

I believe the Specwar 7.62 is rated for the 300 RUM so it should handle the 7mm no problem.
