well its still only an ali barrel with a CF surround,
It isnt an Aluminium wrapped back Lump, it is Stanless Steel like the original Boomstick.
You guys are missing the point of the barrel IMO...
It isnt all about the weight, even though it is our lightest barrel to date. It is the fact that you can hone Stainless Steel finer than Alu (so is smoother), and it is much harder wearing than Alu (so will stay in perfect shooting condition for years).
That coupled with the lightweight CF is an industry first. The processes, time to manufacture and materials involved are why it is more expensive than a UL barrel.
Hope that helps explain it further,
