The learning curve is quite steep for me with regard to the AR platform, so excuse my ignorance. I'd ask on arfcom, but there is almost too much info for a new guy like me. I just want to know what the differences (and advantages) between a "free floating" hanguard, and one that is not?

Free floating handguards do not contact the barrel. The barrel is isolated from the chamber forward. This should enhance long range accuracy as pressure from resting on the handguards is not transfered to the barrel, making for more consistency. It is unlikely you would notice a difference in close range shooting.

Free float will give you better accuracy using a sling, bi-pod, or resting on sandbags, ruck sack or even your hands. The weight of the gun pushes up on the handguards which push up on the barrel causing you Point of Impact to be higher. I personally believe that if you can freefloat a barrel DO IT! Its has no downsides other then a little money. No one has ever said "I like this gun but its just TO accurate."

Thanks. That makes sense.

Any specific recommendations for a FF handguard? I've read that for non-FF, Surefire is the way to go.

You'll have to state your criteria.
Are rails important?
is free float important?
Is cost important?
How far out are you going to be shooting?
Do you want to compete in High Power?

If you aren't going to shoot beyond 100 yards, and are going to use iron sights and the standard trigger, I wouldn't even worry about free float.

Evaluate yourself, are your skills going to surpass the abilities of your equipment?

The standard setup is pretty cheap and easy to upgrade later after you get more experience.

If you are looking for tack driving ability, then free float the barrel, if you just want to plink and be pretty accurate, the normal handguards will suffice.
Having shot a few AR type rifles, I found that my hand usually rests on the mag and not the handguard, but that's just me.
Using a bipod? Free float the barrel.

Also.. what hasn't been said yet.. is the extra weight up front if you use a floating handguard.. the AR will be verry unbalanced....

Depends on your selection of FF tube and amount you want to pay. I got a DanielDefense 7.0 Carbine setup, it's only 8.5 ounces, or 1.8 oz more than a standard carbine handguard once you get it installed. Similar weight changes apply for longer systems as well. The DD stuff is pricey tho.

No way... where did you read that? I'm not saying SF RIS/RAS systems aren't good but IMHO there are better options out there both in quality and in price. i.e. KAC, La Rue, DD, YHM.

Anyway, I posted this a while ago, it might be useful right now because it lets you see some of the differences of most RIS/RAS systems...

I don't think all RIS/RAS systems are built the same. But to be honest, I think you can't go wrong with any manufacturer.
The fact is that there's a lot of options out there. All of them have advantages and disadvantages.

It would be easier to find the best system for you, if you start asking yourself questions like:

*Do you want a FF or non-FF system.
*Are you planning to install the system by yourself? (some require complete disassemble of the upper.)
*Some companies use proprietary barrels.
*What length do you want.
*And yes, the most important... How much money are you willing to spend!

This are some of the companies that produced RIS/RAS systems.

Also, not in the chart you will find:

http://www.vltor.com With their "CASV-EL system"
http://www.surefire.com With their "M72 M73, M81 M82 & M85 systems"
http://www.mgimilitary.com/ With their "MGI QCB system"
http://www.midwestindustriesinc.com/ With their "MCTAR systems".
http://www.samson-mfg.com/ With their "MRFS systems".
http://www.lewismachine.net/ With their "MRP system".

***ETA: The prices of the chart IIRC are from 2003-04***

If money is not an issue, I think this is probably the best system out there: LMT-MRP

If you just want a system that gets the job done at the lowest possible price. I will stick with www.yhm.net by far the best "bang" for the dollar!

And if waiting is not a problem, I will suggest KAC. They are battlefield tested, and they have endure the test of time!

This is my baby, which has been waiting for the delivery of my "CA legal receivers"... :D
