Considering that we now have M4's as a main weapon, the Marines have the M27 as a magazine fed squad auto, and the M249 as a 5.56 MG, is the M63 beginning to look like a serious lack of vision on the part of the US Military?
I'll give you that it needed a good bit of tweaking before it was really ready for prime time, but we could have had a whole lot more versatility out of our small arms a good 40 years ago. I think the military really missed a real opportunity to field what would have eventually become a much superior weapon system.
The problem is, we were just WAY behind on the learning curve when the Stoner came out. The Russians very early saw the need for a mix of weapons such as that, but we were still married to the idea that one rifle would just be everything to everyone. Too bad.
What do you think?
