New guy, first Grendel build

[offensive]

So far my build is as follows:

Aim Surplus Grim Reaper stripped lower
Milspec RifleBuffer and tube
Rock River 2-stage trigger & matched competition lower parts kit
Kies Anti-rotating pins
JP enterprises 3.5lb trigger springs
Kies Oversized take down pins
Magpul BAD lever
Magpul MOE+ grip
Magpul PRS stock


I plan on going with a Nickel-Boron BCG and a 20"-24" barrel, no idea on hand guard, optics, comp or brake or bipod yet.
