Just sold my .338 Federal AR-10 upper to a friend...
I kept the .358 Winchesters and the .308s... working on some .458 WM AR-10s
.308s are the most common AR-10s obviously.
Who else has other calibers and do you like them?
Calibers like .22-250, 243W, .260R, 6.5CM, 7mm-08, .375 Raptor, .45 Raptor etc. I could go on, but you get the idea.
Be verdant... NOT petulant... in all things.
I-95 "Fast Lanes" solved NOTHING!!!
