All the time, but probably not for the reasons you think. A wonderful example would be a certain mfgs pint glass that I've been drinking out of for the last 10 years or so. It will never come to market.

Ok so what does this Upper do demonstrably that a standard Upper does not?

IMHO, this upper should improve accuracy and bolt life to some degree. Also, the relocated FA position should also make right side FA manipulation a little easier. Nothing is so good it cannot be made better, even if it maybe somewhat incremental. For example, the trigger and the accuracy of the Gen 5 Glocks compared to the earlier generations. Another example is, BCM tightening up the ID spec of the upper for the barrel extension to enhance accuracy. Another example would be the soon to be released Surefire optimized bolt carrier, that will increase an AR’s reliability and bolt life. Also, look at KAC and their many innovations that make a better AR15. In the arms race nothing stays the same, things are improved upon and at some point replaced. Then again, some people are perfectly content driving their model T.

Biggest thing I would think of is making that ambi charging handle easier to use. If you use the right side of those charging handles the forward assist kinda gets in the way of you racking the handle. Looks to be far enough forward that if you tried using that side of the charging handle on both I think one would see the difference right away.

Might help with some sling mounts getting in the way as well(of the forward assist) but I don't know if that would really be noticeable because you don't really ever use the f/a. As far as the claim its stronger it very well might be. I don't know if that is really something that was needed but if its not adding weight I don't see the problem.

All you guys talking about the forward assist need to jump on that Forward Controls Design LDFA train if you haven’t already.
