I have emailed and talked to the owner of grendelhunter.com. Guy seems like a straight shooter. He even went as far as putting some different forearms on his uppers to give me exact weights. Every time I emailed him I got a response within a few hours. They offer a %5 military discount. I am going to end up building my own upper so I won't be purchasing one of his but just wanted everyone to know that the company seems like a good place to do business.
My main concern was I will primarily be shooting factory ammo and by a few accounts the grendel 2 chambers are shooting the factory ammo pretty slow( don't know this just what I have read). They supposedly can be handloaded hotter than the sammi spec( don't know this just what I have read). Since I wanted the best velocity I could get with factory loads and still have a fairly light upper I went with a alexander arms 18" fluted barrel.
