Hello guys, this is my first time building an AR, a decided I'd like to build my version of a mk12 or spr. I'd like this to be a high end build and I'm open to suggestions. I'd like to use as much carbon fiber as possible and make it as lite weight as I can. What started this was a hand guard I purchased thinking it was for an ar 10 , turned it it was for a 15. He handguard is a Christensen arms carbon fiber. I'd love to attach pics if someone can explain to me how.
First grendel build

I'll be buying 2 of Eisenachs nitrided BCGs as soon as I sell some C&R stuff.
Get yourself a nice ambi lower. Rainier Arms makes a very nice one with build in ambi bolt release and mag release. CMT also makes one that is logo/rollmark free but it's half an ounce heavier than Rainier's. Mega makes the lightest ambi lower but it doesn't have the built in ambi mag release. Not a huge deal since you can just pick one up from High Velocity Arms.
High end? Just get yourself a Fostech Echo trigger. The new gen works with any M16 cut BCG (which the Eisenach is). If that's not your thing, Geissele is always a safe bet.
Take a look at the Precision Armament EFAB flashcomp if you don't plan on running a suppressor. If you do, I'd suggest a KAC MAMS.
For a lightweight CF stock, as I recommended in another thread, the Lancer CF. I have one and don't think you can beat it for the price.
I've got 4 builds going right now with 2-3 more in the works. Always glad to help others spend their $.

Thank you for the reply! I'm new to this, never had or fired a grendel but it seems like the perfect caliber to make my "improved" mk 12. Was thinking a proof research barrel or a Christensen arms( the proof seems to only come in 20 vs a Christensen arms 18) but would the 20 look crazy with my shorter handguard?

If you're primarily used to AR15s, choose your own adventure (Ascend Armory's matched billet ambi set would be my choice if I were in the market for a standard setup).
I have 2 Lantacs and a Mega side charging upper. I'm waiting for CMT to get theirs back in stock for a lightweight recon build. Eisenach splits the weight difference.
Oh, also I recommend Alexander Arms Hard Use 6.5 bolt. The ionbond coating is superior to anything else out there

A1 or A2 is about a half inch length of pull difference. Go with either one. I'm betting you'll never notice (I bought the A2 FWIW).
