Home Forums Hunting & Shooting AR and Tactical Rifles AR 10 build - barrel length and profile recommendations?

Having owned the S&W MP-10 with a light profile barrel, I really thought it would be the way to go for a field rifle. After about a year of trying various loads, I couldn't get it under a couple inches with any of them. It shoot pretty much everything OK, but nothing really great.

The accuracy would have covered everything I want do, but the excess weight and the accuracy difference between the AR and a bolt rifle pushed me to let it go.

I would agree that the heavy barrel, while less carry-able, is probably going to be better on the firing line than a light profile one.

Ballistics Advantage makes barrels for Aero, and seem to have a good reputation for casual shooters. I'm finishing a 6.5 CM upper at the moment, like the OP, I had the parts...
