ga precision is known to have one of the most of not the most accurate production 308 semi auto rifle. They happen to use Seekins to build their billet receiver set. Why? Bc Seekins precision makes good products.

So I guess so long as you’re not planning to drive over your rifle with a truck, billet should be ok.
And the talk about aesthetics is just one advantage of a billet receiver. You fail to mention the additional feature some of them add like the ambi controls, built in QD sockets, flared magwells, etc
