nice setup Variable. i really like the short barrel in the 6.5 and i can shoot mine without hearing protection with my 308 suppressor. very quiet actually, and the downrange performance is outstanding compared to the 223 obviously. its great to have such a fine cartridge that'll work in the AR platform without the heavy weight of the AR10. that was the main selling point for me. i was on the fence for about 6 months trying to decide between the 6.8 or the 6.5, as i had read that the 6.8 was supposidly very efficient in short barrels. not sure if the same can be said for the 6.5 but i suspect it is as i dont get a flame thrower effect when shooting without suppressor attached. cant say that for the 223 as it'll cook bacon when running a shorty. i had to tinker with several different buffer weights in mine before it would run on full auto without and with the suppressor, and since figuring that out its been 100% since. i'd like to tinker with some subsonic loads if there's some data that indicates it'll cycle the action, but now that the 6.5 has been unleashed via SAMI specs and whatnot, i figure it wont be long till somebody comes up with a subsonic load that might work.
