Car-a3 Hbar Elite

I have a colt HBAR and was wondering why it seems like you never see anyone building on a colt. Is there something wrong with Colt? Bought mine from Daves guns a few years ago and it's accurate, reliable. Never have shot another AR to compare it to.
Also in the name of saving life on the barrel I'd like to add an upper that I could switch out that has a shorter (than 24") maybe like 18ish. Something I don't care if it gets REALLY hot from shooting up cheep ammo. What upper would you go with?[AR15]

P.S. Why Does it say 5.56 Nato on Barrel and 223 on lower reciver? I know about shooting 5.56 in a 223 is a no no but ok the other way around....right?????

I thought 5.56 and .223 were the same thing, and 7.62 NATO and .308 Win. were the same thing.....

Supposed to be higher pressure for the military stuff....I belive

The numbers on the lower receiver do not affect anything. The lower receiver just holds everything in place and has nothing to do with what ammo you can fire. Some manufactures write the "intended" caliber on the lower, while others leave it blank.

The numbers on the barrel matter. You can safely fire .223 ammo in a rifle chambered for 5.56 but not the other way around.

So it is a very good thing that your rifle is chambered in 5.56mm ammo. Good for you. You can shoot military surplus 5.56mm ammo and commercial .223 ammo safely.

As for Colt...they are great...they are just next to impossible to find and usually cost 3 times as much as the competition when all the specs are even.

There are varring qualities of parts and uppers with every brand name, including Colt. Meaning Colt makes low end stuff, and high-end stuff. It all comes down to the details. Is it chrome-lined? What is the twist rate? Does it have M4 feed ramps? All questions that will help you judge the quality of your rifle.

If all you do is go plinking every so often...just about anything will do. If you want to have the Ferrari of AR-15's...the details come into play!

Hope that helps...just trying to earn my keep.
