Most reliable BCG for Grendel pistol?

[Growler]

You seem to have had a mixed experience with LMT; would you still recommend them? With more searching I found a non-enhanced LMT carrier for $120; completed it would be about the same as the Geissele.

Still don’t have enough rounds on my LMT enhanced BCG to give an opinion. So far, it’s fine. My build philosophy changed after I put it together and that is the reason for the low rounds count on it. Originally, I planned to use a fixed gas block on a shorter barrel—that’s the gas management issue it was designed to band-aid. I’m now running adjustable gas blocks and tuning for specific loads. This approach is a trade-off. Not as reliable for temperature extremes or light loads, but it runs much smoother.

I originally bought an unusual version, carrier only (no bolt). I got a one-off result. Can’t judge LMT or any other manufacturer for that, as Murphy plays in one-off situations. When I returned it for a complete BCG, I got a smooth finished, tight little gem. Customer service was great.
