Question for all of the LaRue UU 308 owners

What lowers are compatible with the upper? I'm looking for something with ambi bolt catch / release. My Seekins SP10 lower fit but the bolt catch rubs on the upper. LaRue told me LMT and KAC should work because they were M110 cut, but wouldn't confirm 100%

Interested in hearing what some of you have tried and worked well.

Thanks
 
Mega is another know to work.
Stag can be made to work (some filing/fitting for the rear lug), but many of the LaRue small parts for the lower are not compatible and need the Stag LPK to finish it out.

Can you post a pic of where the SP10 make contact.
