What’s everyone’s go-to BCG?

I’m asking what your go-to bcg is, when it comes to functionality and reliability.

The SOLGW chrome bcg (pictured) has ran flawlessly so far. The only concern I have is when I remove the bcg from the receiver and stand it upright on the bolt, it falls every time. I know this suggests blown gas rings. But if it still cycles the gun normally, is it bad?

Also, Merry Christmas Eve!
