My First grendel build

[mel]

if u have keymod or m-lok slots all down ur handguard at the bottom the best way i see to attach it is just bolt the arca plate right to the handgaurd and forget any kind of adapter

those 2 lil round nubs on the bottom of the plate are the exact spacing u need for keymod so if u drill the right size hole in those for the keymod screws , then u just grind the nubs off so the plate is flat on the bottom and u can countersink the screws in , and then a lil work on the other side with a die grinder to make room for the keymod nuts and it will go right on , m-lok is as easy as drilling 2 holes and grinding whats left of the nubs flat with the plate and ur good to go

and for what its worth the plastic plate which is easier to mod holds up my 23 pound ( with night setup on it) ar-10 just fine
