556 PredatAR delivered to my ffl only 11 days after order. Won't get to shoot it until Mon. but I'm in love. I'd been wanting a pencil barrel for awhile and price was right for my first Larue. Skinny forearm is awesome. Poor point and shoot camera but the rifle is artwork. I thought there was some kind of newfangled catch machined somewhere as I couldn't get the halves seperated at first without a fight because it is so tight, unreal tight. Is this standard with Larue rifles? Still contemplating optic and light choice because the rifle is so light and nice.
