Good day guys, I have recently got into hunting and determined that a 300 blkout round is a great way to go specific to hunting.  I have an AR already chambered 223/556 but it just doesn't have the punch that I've come to understand is better to have than not to have.  I've come up with a list of questions that maybe some of you have encountered or may just know.

1 -Would it make more sense to just buy a 300 upper and switch up when I go hunting or buy a whole new rifle?[/li]

2 -If I were to go the buying a new rifle route, one of my co-workers recommended a diamondback (he says it will shoot 223/556/300 with the same bolt??) Is this a good choice for the 300 AR?[/li]

3 -What is a reasonable price for a quality (budget?) 300 upper only?[*]

4 -Is 850 reasonable for the Diamondback brand mentioned earlier?[*]

Any other knowledge you could impart on me would be appreciated.  Thank you for your time

1.) I would just get a new upper
2.) 300blk and 5.56/.223 use the same bolt in every rifle. The only difference these calibers have as far as the gun is concerned is the barrel.
As for questions 3 and 4 I'm really not too familiar with Diamondback so I will let someone else take it from here.

In response to question number 2.

While it is true the bolt is the same, 300 is made out of a .223 case, the diameter of bullet is different. You would need a different barrel.

Edit: .224 vs .308

Thanks for the responses guys, I think I found one of my answers
