My Grendel AR upper

[earlwb]

Very fun! I like those side chargers as well. Be careful with the exposed gas block and tube. They get hot and can leak a little as well. Don't burn your hand.

Thanks, yeah I was thinking about that myself too. Fortunately I am right handed, so that keeps my front arm out of the way. I think that one definitely needs the screw in back plug for the rear where the charging handle used to be. That keeps any blow by gasses from coming at your eye and face.
