I have been trying to figure out how to search this forum, and everything is coming up "No Topics Found" and then there is a time restriction between searches.  Hopefully I can figure it out.

But in the meantime, I am starting my build with the lower and I have few questions.  My lower is Multi Cal and I am wanting to build it for the .308 round.  Is their a specific trigger that I will need specifically for the .308 verses the .223?  Or will one trigger work with both rounds?

Also, I am looking into the CMMG lower kit, are there other lower kits out there that I should consider?  Are there lower kits without the triggers and grip?  I am thinking, no sense paying for a trigger if I am just going to get an upgraded one.

Thanks for the time and help, I am looking forward to working with my build and learning more about the AR-15.  And if there is anything else I should be considering please feel free to let me know.

I can't comment on specific .308 triggers, but I'd caution you to make sure your lower is indeed a .308 lower. Usually lowers labelled "multi-cal" are .223/5.56/9mm lowers.

The easiest way to search this site is to use Google. put "site:ar15.com" or just "ar15.com" at the end of your search and you'll get relevant results.

Thanks for the clarification!!

I just called the company that made the lower and you're correct, they said the .308 is a larger platform.  Not a problem for me, just thought it would be nice to build a .308.

But all my other questions still stand.

You do have 300 Blackout as a .30cal option.  Build just like it was 5.56 but with the BO barrel.

Look at Red Barn Armory for the most LPK flexibility.  You can upgrade FCG and/or the grip to your liking.  Real handy.

Cool. Glad that got sorted out.

Did a little looking around, and it looks like you can use standard AR triggers in a .308.

Yes, standard AR triggers work in a .308 AR.  Palmetto State sells lower parts kits without the FCG (fire control group) if you're wanting to save some money.  
Or you can get kits that have a variety of different grips and/or triggers.  http://palmettostatearmory.com/ar-15-05/lower-parts/parts-kits.html?p=1

For example, they sell lower parts kits with an upgraded trigger already included.  LPK-G for the Geissele SSA - HERE
and the LPK-E with the Geissele SSA-E - HERE
