First, I learned that it is brutally cold out there - -12F. :( Brr brrrrr brrrr
And second, if I had any affection for the M16 before, it's gone now. All weekend, from Friday afternoon till Saturday night, they simply would not work. We used CLP, LAW and LSA, and nothing made them work. The bolts wouldn't go back, they'd lock back, they'd go forward partway. I carried a SAW all weekend and it never, ever malfunctioned despite the bitter cold, rough use and lack of care. The poor riflemen were cleaning and lubing at every chance, and the darn 16s still wouldnt work. I would far rather hump miles and run across a field at high ready with a SAW that works than any M16 clone that doesn't.
If there are any fans of the finicky M16, and I'm sure their are, just note that in my 13 years, they have given me and everyone I know nothing but trouble. There is a reason I jump on the SAW or M14 given the slightest chance.
M16s are nothing but garbage. And I hate them more now than ever.
