Anyone try the Aero adjustable gas block?

[SDW]

I couldn't resist. Ordered one from Optics Planet. I don't really need an adjustable GB for my upcoming build, but $48 with free shipping put it within $5-10 of my usual go-to, a BCM GB. And who knows. Might come in handy. I'm curious to see how long it actually takes to arrive. 5 - 7 weeks they're saying now. No rush on my end because I still need an upper receiver, and those seem to be even more scarce these days
