Why would I want to get a heavy match barrel instead of a regular one? What would be the advantage?

For bench shooting, a heavy barrel has less vibration and heats up slower. For any hunting and carrying, I use a light barrel.

If you want to shoot in High Power competition, then you'll want a heavy profile match barrel and lead weights in the furniture.

For casual shooting, the lightweight barrel is my preference.

How much more does the Heavy Barrel weigh? Would it be harder to hold steady when shooting?

The 20" HBAR is 3.5 lbs, a 20" Govt profile is 2.5lbs. That's a savings of 1lb. The A1 profile (superlight or pencil barrel) like on my rifle above is even lighter than the Govt profile, but I can't remember how much.

From the Bushmaster FAQ.

My target AR has a 24" bull barrel mounted on a standard A-2 lower. When I first assembled it, I was surprised how out of balance it was. I put a lead counterweight in the buttstock compartment. Now the rifle weighs 13lbs, it holds rock steady off hand, and sits solidly on the bench. I wouldn't change a thing about it, but I will say I wouldn't want this to be my only AR.

Unless you are target shooting with your AR you don't really need the heavy barrel. The AR platform is at its best as a fast handling lightweight weapon. I have a standard barrel on my coyote hunting AR. Easier to pack around between setups. If you own more than one you could have light field gun and a heavy barreled bench gun. I still prefer a bolt action rifle for target shooting from the bench. JMHO

"Do you shoot it unrested? "

Yes, I rest the rifle magazine on my left palm and my left elbow on top of my hip. I like magazines that are almost flush with the mag well. You just cant take all day to take your shots.
