Has anyone here had any experience with a 2A Armament BALIOS-Lite Upper? The specs look great with 5.85 oz stripped. I haven't been able to find much on reviews, it looks like they are a brand new company from what I've been able to find on ar15.com.
Would it be a concern having a lightweight upper with thin walls for the Grendel?
