bgb,
Same bolt, Beo upper will work fine for Grendel, but not the reverse, because the Grendel port is smaller and narrower than the Beo port.
BUT....Uppers are cheap, (less than $100), so why kill your Beo to build a Grendel? Everything else is usuable in both, so I would just pick up another upper to build the Grendel.

You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
