I shot 3 yotes out of 1 pack 1 afternoon, just before dark. Before using my AR15 on yotes, the best I could do was 1 yote at a time.
That must have been awesome excitement
And another question is: are these guns free-floated? I know that in some specifications or details it will say that the barrel is free floated. If its not could that turn into a potential accuracy problem or not?
No. It has standard hanguards. You can buy an aftermarket free float foreend for under $100where you simply(its not that simple, but its not hard to do) replace the barrel nut, gas tube, and foreend to have a free floated barrel. The only downside is that you need about $70 worth of tools to do this (receiver vise and AR-15 wrench).
Accuracywise, a free float tube on an AR-15 can make a world of difference. I wouldn't expect a non-free floated AR to shoot much better than 2 moa, a free floated rifle should shootmoa or better.
