I think my head is going to explode............(updated, sort of, post 32)

For unknown reasons, the last M1A on which I installed an 18" barrel refused to shoot as well. Horrible accuracy. But both of the random 22" barrels have been OK both before and after the 18" bbl install. On the other hand, a SAGE stock equipped 18" standard SAInc. rifle has been very, very accurate.

As far as front band fit, it needs to make no contact on it's rear face with the front of the stock. It also needs to have ~3-5 lbs tension between the lip and the bottom of the stock and be well centered. The handguard should not touch the stock. The triggerguard should take some force to close. There's lots more, but those are good starting points.
