Which barrel weight would be best for an XCR that would see use both with and without a suppressor? It would be an AAC m4-1000 FWIW, and 16" barrel. Would the lightweight barrel work ok in this application, or is the heavy barrel recommended? I like to keep the weight down, but in this case it may not be worth it. If I'm going to spend the money on one of these carbines, I need to make sure it's fully thought out. This would really just be a range toy, but if it proves to be better than my other guns it may end up becoming my go to SHTF carbine.
