re: #205 wlewisiii

Depends on if you reload. H&K is seriously harsh on the brass. ;) What I really want is a FAL based rifle in 5.56 but they’re few and far between.

There is a problem whenever reloaders gets too much say in military weapon design…

en.wikipedia.org

Excerpt:
Another drawback was that the gun was fed by 20-round strips of cartridges. This limited continuous fire, as the gun could only be fired rapidly when a second crew member fed in one ammunition strip after another. The rounds still had to be oiled to stop the cases sticking in the chamber, with all the disadvantages this entailed. Another peculiarity of the design is that the spent cases were reinserted into the strip as each round was fired. The mechanical energy required to perform this function substantially reduced the rate of fire, and the weapon tended to jam whenever a case was reinserted even slightly out of line. It also meant that in the event the metal clips had to be reused, the gunner’s assistant had to first remove the empty cases from the strips.
