Larue Ultimate Upper Large frame barrel compatibility

[Ale80]

Hello everyone! Apologies if this was answered somewhere else, I just received my 6.5 creedmoor UU kit today (first time Larue owner!). I wanted to make sure, but are the large frame UU kits compatible with standard AR308 (faxon/rainier/ballistic advantage) barrels? Planning for a potential future replacement.

Thanks in advance!

Yes, the part of the barrel extension that slides into the upper receiver and mates up against the face of the upper receiver are all the same. You just have to make sure you're running a compatible bolt that has been headspace properly for the style of barrel extension you have.

Thanks, that opens up quite a few more options.
