The UK had to spend a further 90 million £ years later on to replace many of the working parts, after they contracted Heckler and Koch to find and deal with the inherent faults in it.

I would love to make a flat sided version of this upper like the Leader or Vulcan. After seeing and handling the parts, does it look much harder to do than an AK receiver? Perhaps it is the trunion set up that is the sticking point. It just seems so simple to my untrained eye but there must be something difficult about it or is it that is only inexpensive to produce when production is scaled up?
