thanks for the links Big-FED
hIts a RRA so it's button-rifled. It's a sub MOA bbl now and I've been very please with the accuracy but after reading the threads, I'm a little apprehensive about even having it turned down under the h/g because of the stress factors but I would like to have it a little more carry friendly while walking around the "back 40" with it.
How much can it be turned down with minimal risk of the accuracy being influenced ??
