It works
Everything was there. It works. Nothing was missing or odd-sized for the parts kit.

Good LPK, shipped fast
CMMG has always made some good parts, and this isn't an exception. Grabagun has gotten some mixed reviews online so I was a little hesitant but hoping for the best. Parts came in quick, everything was there, and it was legit CMMG parts. There is also a QR code for easy assembly for turning the LPK and a stripped lower to a functioning lower minus the stock, buffer tube and castle nut parts. Good price, and great shipping, if I find myself building another AR, I'd definitely get i here again.

Best available!
The price seemed a little high but at least it was in stock. The trigger was a little better without any work than other kits I put together.
