Lightweight Grendel - round 2

[Drifter]

I don't know if I can shave off additional weight by replacing the Magpul MOE stock...any suggestions?

Doubtful on that one. But depending upon how your setup is operating, you might could use a lighter buffer weight, and maybe a lighter bolt carrier too. Look at the JPE LMOS (sp?) components. Perhaps this 1.7 oz gas block would allow tuning your system to work with the lighter components:

(Also sold via MidwayUSA under the AR-Stoner brand name.)

Bet you could shave another quarter pound or more with the buffer and bolt carrier.
