I just bought a used AR-10T in .243 with a 26" Rock bbl. First three shots were less than 1/2" at 100 yds. That was just for sighting in and with a run of the mil-spec trigger (I'm the third owner, previous owner took out the NM trigger, looking at several options now, leaning towards the Geissele HS match. I tend to like Armalite AR-10 platform guns over others. I don't know if it's near AR-15 mil spec aesthetics or their parkerization or what. I do jones for a p-mag that would fit instead of or in addition to the M-14 style. Are you listening Magpul??
Armalite still makes one in .243 win. Better decide right now what twist you want. Some of the long range crowd are going tighter twist to use the 107gr- 115gr pills. I've got a normal factory twist of 1/9 so I'll be limited to @100gr bullets.
Good luck.
