Nope, these are just off-the-rack (of course, freshly arsenal-reconditioned) M14s. Some with wood, some with plastic stocks. Not national match, not special selection, no aftermarket parts. The only change from the way they were issued 1957-65 or so is the rails system.
A lot of the civilian M1As have cheap, investment-cast receivers which leads to problems in heavy use; they'd never pass Army testing. Most people don't shoot them enough to have any problems, though. Beware the Chinese imports particularly, some of them have come apart on people.
