I had an MOE handguard on my 6920 and there was absolutely nothing wrong with it. It was comfortable, fairly light, and had a heat shield. I can shoot all day long without gloves. Absolutely no reason to replace it.
So I replaced it.
I guess I spend too much time here.
I didn't want to remove the barrel nut or FSB on this AR. It works like a Timex and I'd rather leave well enough alone, so I looked at my drop-in options. I wasn't too concerned about price, so a KAC RAS was at the top of my list. Since I wasn't looking to clone an M4, the Omega was also a contender. After looking at both, the Omega won:
- lighter
- thinner
- free-float
- continuous top
- built-in QD connectors
The result - wow. Easy shouldn't be this good.
Installation took about 10 minutes and it is rock solid. Pics below for anyone who may be considering picking one up.
