New Toy - LaRue Tactical 6.5 Grendel

I don't have a dedicated lower for this yet, so I just threw it on my S&W lower for now. LaRue Tactical Stealth 6.5 Grendel 18" barrel 1/7 twist. I've got flip-up sights and rail covers on the way. Still deciding on the optic, but I'm leaning toward another Holosun HS510c with the 3X magnifier behind it. This is probably more suited for a scope, but I've already got that on my 20" Grendel. Wanted to give LaRue a try and put together another Grendel gun. If Optics Planet used a better shipping method, I'd have it at the range tomorrow. :(
