[ARCHIVED THREAD] - Grendel 6.5 Question

Posted: 1/16/2011 8:24:57 PM EDT

Question for the group:

I recently ordered a Alexander Arms GSR 6.5 upper. The upper has a Satern barrel with a 3/4-28tpi threading.

I have a 6.8 and a 7.62 AAC SPRM4 cans.

First, what type of adapter do I need to use one of these on my new 6.5?

and second, which of these will work the best?The thread pitch on the MITER QD is 5/8-24.

Any suggestions would be appreciated.
