standard MOE grip
I've tried just about everything..........favorite is the MIAD with the B3 back (large) and the F1 front (no A2 spike) Wish Magpul would have made the integrated trigger guard with the plain front strap instead of the stupid A2 spike.
That combo would be #1 in my book.
2nd goes to the MOE, 3rd to the BCM GunFighter Mod1, 4th to the TangoDown BG17, 5th to the MOE+
