*strictly speculation here*
CMMG is making SOME of the parts for FFE. But we still don't know if CMMG is manufacturing ALL the parts for THEIR guns.
I'd bet on the LPK, buffer/tube, and the sights being left over parts. Maybe even the BCG as well. Probably DPMS.
I'm sure it will function perfectly. But don't think your getting a CMMG gun for that price. CMMG would be cutting their own throats if a FFE rifle and a CMMG rifle were the exact same thing. I'm sure QC isn't as good as a regular CMMG rifle either.
Take this for what's it's worth...........just and opinion.
Here are some links where FFE is mentioned. Read up. Talk to some FFE owners.
