Default New to AR. Must have one.

So here go the dumb questions:
  1. What is the opinion of the Sig 5.56?
  1. Is it customizable?
  1. If a 223 will accept 5.56 ammo, why are Sig and Ruger calling theirs 5.56?

That will be all for now, but more dumb questions to follow. Thanks.

1. - Sig makes a nice rifle. They have a patented two valve system for their recoil operation. It's pretty slick. That said, you are paying a lot for the name. Not the rifle isn't a good one, it is, but you are well above the price of a comparably equipped stick that you can customize and work on yourself.

2. - I believe there are little things that you can do to the rifle, but your standard AR parts aren't going to fit it. I am sure the pistol grip can be changed. The front foreend ( I do not believe ) is free floated on the basic service rifle, so I don't know if an aftermarket foreend will fit or not, I have never work on one.

3. - You have this reversed. A 5.56 chamber will accept the lighter, civilian .223 rounds. A .223 chamber is NOT rated to accept the heavier 5.56 military pressure loads. Sig and other companies are marketing 5.56mm chambers because that is the safer bet in sales. Customers can still shoot either round, but the 5.56 round will achieve better accuracy.

One thing to note, Sig uses Cold Hammer Forged Barrels, which are more accurate than chrome lined, but not as durable in the long run if you are going to put thousands upon thousands of rounds down range on a regualr basis...

Based on what you said, I think I'll take a pass. Really expensive at $1,799...although it DID have a quad rail and a flashlight!

I went to look at it at my local shop and asked him the question, "why do some ARs say they are chambered in .223 and accept 5.56 while the Sigs and Rugers say they are 5.56?" He said that 556 is just the model name of those particular rifles.

Still haven't ruled out your recommendation of putting one together myself....but I'm pretty time-challenged at times.

Now, you're going to say that all the time I spend on the FTF, I could be building an AR. And, of course, I would have no response to that.

+1 what ^ said

You would have a very Name-brand AR, score high in Styling-points, but would not be able to customize it very easily or affordably.

and the ergonomics SUUUUUUUUUUUUUUUUUUUUUUUUUUUCKKKKKK.

Good choice passing on it. Colt LE 6920s are way down right now, $1150 if you shop. SW MP 15s are are pretty good choice too, much cheaper but if price isnt an issue, get the Pony.

Let us know what you get!

I knew I could count on you guys. I'll let y'all know what I end up with. Big gun show in Fort Worth January 3 (if I can a wait that long without buying myself an early Christmas gift). I'll probably pull the trigger then. No pun intended.
