For anyone that is wondering, a SilencerCo 3-lug adapter fits just fine.

I can't help you much with that. I am pretty sure that the Griffin 3-lug adapter is shorter than the SilencerCo adapter by a little more than an inch, but I'm not sure about the OD of the spring collar. I don't think that the length of the adapter would cause any issue.
From my eyeball estimate, the spring collar of the SilencerCo adapter has about 1/16" clearance with the inside of the rail.
