John, is that bushmaster SIR permanently fixed?  I know there is a military and civilian version of the ARMS S.I.R.  The mil version needs gunsmithing and removal of the slip ring, and the civ version simply attaches like a normal foregrip (in addition to affixing the upper rail sleeve).
Heres my question of the day:  What does the term FLOATING refer to?  I hear it alot, but am unsure as to its definition.  I am under the impression it means it does not constrict the barrel, but I'm not sure how, or why this matters.  Please explain!

Floating means the barrel isn't touching anything but the receiver, correct?

so all accessories, such as a RIS or SIR woiuld simply be attached via the reciever?  This makes sense in the case of the SIR due to the sleeve that attaches to the reciever rail, but confounds me in the case of the RIS or RAS, as it appears to only attach via the barrel, like a regular foregrip.  ????

"Floating" on an AR is something of a misnomer. To me, it just means a couple less things are touching the barrel. An AR will always have a few things in contact with the barrel.

The KAC RIS/RAS were never considered "Floating" handguards AFAIK.  I know mine is not.

The Bushmaster one is the Military version.  It replaces the delta ring and is permanently attached.

Yes you can free float an AR barrel.  The easiest way is to get a free float hand guard tube that attaches via where the Delta ring goes.  It replaces the barrel nut and completely isolates the barrel from any tension.

and that increases accuracy by not  constricting the barrel?

No matter what, though, the gas tube still contacts the barrel via the front 'sight' and goes back to the receiver. So still technically not free-floated. But I know you can eliminate the handguard from touching the barrel. In fact, that barrel nut touches the barrel too, doesn't it? Or does it just come in contact with the upper receiver?

Yes, Christian, pretty much any time you can have the barrel not in contact with any other part of the gun, accuracy increases. In <i>MOST</i> cases. Nothing to interfere with the barrel harmonics, or as my dad always called it, barrel whip. That is why a free-floated, bull barrel is the preferrence of snipers, varmint hunters, or anyone else who wants the most accuracy they can get.

The gas tube is inconsequential.  There's no tension what so ever from that.  Yes the barrel nut touches the barrel, it has to in order to secure the barrel to the receiver.  Nothing different that a bolt action guns barrel being mounted to its receiver.  The "free float" part is in regards to the rest of the barrel not the attachment point.

KAC RAS on M4
« Reply #44 on: August 20, 2003, 09:37:37 AM »
I just acquired a KAC (Knight's Armament Co.) RAS to put on my RRA M4.  I can't wait to get home and "install" it.  [:D]

I'll post some pictures this evening.
