Looking for home defense purpose.  Is the Colt CLT CRXM177E2 a good, better or best AR weapon for the money? (approx. $2700).  Also, what's the difference between 223 rem and 556 nato? Are they one in the same?  Thanks 

So many better AR platform guns out there for the price.  I would even look at a Non-NFA "Other" Firearm (AR type) like the Troy A4 Other.  

The chamber dimensions for the 5.56 are slightly larger than a .223 chamber.  The leade (or throat) is the area between the front of the chamber and the point where the bullet itself connects with the rifling.  5.56 rounds are slightly longer than .223, which means 5.56 ammo can be a little bit hotter, and cause overpressure in a .223 chamber.  Basically - get an AR with a barrel chambered in 5.56 or .223 Wylde.  That means it can shoot both 5.56 and .223 safely.

My friend that is such a loaded question...lol. In my humble opinion as a noob myself I've researched this pretty deep and just bought my first AR-15. There are so many options, features and accessories. I just bought Precision Firearms Katana 3 tactical AR-15

• Samurai 13 inch handguard Mlok

• PF LMD Brake , Optional PF NOX Flash Hider

• BCM Gunfighter Mod 4 Charging handle
• Milspec 7075-T6 Buffer Tube (not the cheap 6061 tubes common on the market now)
• Magpul ACS-L Stock or Magpul STR or BCM SopMod
•  Magpul AFG

$1900 give or take.

You really should learn as much as you can about all aspects of the riffle. Just humble advise from a guy that didn't know this was so deep! Also keep in mind if that riffle is used in a HD situation .....it will be taken by the police.

There are many very fine ARs for home defense that can be had for under $1000.  IMHO you will not be any safer/better off by spending more than that.

This article might be helpful.
