I really like the build! If it were mine, the only thing I would change is the light setup. I would buy the magpul illumination kit when it becomes available, and run the G2 on the canteliver rail mount that comes with the kit.
First I’ve seen of the new Magpul handguards, very nice. I also appreciate your light mount, Keeping the light in line with your bore really makes sense. Almost a shame it’s gonna git skint up and lookin like it’s been shot…A lot hopefully! Congrats!
