well since he didn' t ask about the " T" and I didn' t mention the " T" and since I' ve never shot the " T" and only the regular AR-10 I don' t know [8D]

The AR-10' s that I shot were not as accurate as the M1A' s I have shot. Just my opion and they were getting about 2" at 100 yards (ar-10' s) that is.
