Jeff - the rifle linked here has a 'heavy barrel'. Note the difference. budsgunshop.com/catalog/product_info.php/products_id/13232/bushmaster+90280+le+30%2b1+223rem%2f556nato+16%22+a3

No this is not a heavy barrel it is a standard M4 barrel

Jeff - this is not a 'heavy barrel'. If you are looking for a rifle to meet state restrictions that call for a 'heavy barrel', this one will not qualify with the M4 cut in it. Some states that restrict AR ownership to the rifles with a heavy barrel specify 'no cuts in barrel'. This will not meet those requirements ... such as in Maryland.

Jeff, yes this is M4 Heavy Barrel. It is a 16" M4 Profile 4150 Chrome-Moly Steel Barrel. This puts the weight over 8lbs. Still, please confirm with Bushmaster Customer Service at 1-800-883-6229 or by email submission : bushmaster.com/contact (There are HBAR M4 Barrels) : google.com/search?q=m4+vs+hbar&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjQtK6Ypp7hAhWGneAKHfCoDYcQ_AUIDigB&biw=1280&bih=596#imgrc=k48uk7VEt4a-3M:

Jeff, yes this is M4 Heavy Barrel. It is a 16" M4 Profile 4150 Chrome-Moly Steel Barrel.

Jeff - No sir, this gun has a 16" M4 Profile 4150 Chrome-Moly Steel Barrel with a 1:9 Twist. The HBAR barrels won't have the 'govt cut out' in them - same size all the way out from the gas block to the muzzle.
