Personally, I'm a guy that likes to modify anything and everything that can be modified. So, that said, I would prefer an unpinned flash suppressor if it means having the 16" barrel.

However, with the introduction of a new rifle into the US market, it's quite a gamble to change the design/manufacturing process. Albeit, it's a rather small difference/alteration; it most likely won't pose much difficulty.

Keep a good design a good design. If there's nothing wrong, don't change it. When the Tavor gains more popularity, only then should we introduce options for customization.

Cosmetically, an extra 1.5 inches sticking out looks a bit out of place for a 16" barrel. I don't think consumers would like this. On top of that, I don't think the majority of consumers modify their weapons much beyond their "out-of-the-box" condition.

From a business perspective, I would choose to stick with the stock barrel and a pinned flash suppressor.
