I want to do a "precision" semi auto AR and have it boiled down to these 2 calibers. I know the BRX is off the AR15 and the 6CM is off an AR10. Has anybody messed with both yet?
I have been following that build, I think I'm going to do both but I'm trying to figure out which one to do first. I was just mainly curious how the 6BRX feeds.
