I'm a newb to AR's. I've been researching the AR's and I'm left wondering where in the world do I start when it comes to picking a upper and lower.
One of the things I keep bumping into is billet based upper and lowers in 6061-T6 and 7071-T6 alloys. As the subject title states (or inquires) what are the pro's vs con's of two alloys? Is one preferred over the other?
Thanks for the bandwidth!
