Assuming we are talking a 16" barrel:
-Remove the flash hider -Knock out the taper pins, and remove the FSB, cap, and gas tube -Remove the barrel nut, and take off the delta ring -Reinstall the barrel nut if you are going to install a FF handguard that mounts on a standard nut Reassemble with a lo-pro gas block, or you can chop the FSB, if you like, and make your own |

So to do this I need to get all the tools for removing the barrel. And access to a vice clamp. Thanks for the info! |

Daniel defense makes a quad rail that is a two piece free float "omega". MI also makes a two piece quad and a keymod two piece that are a little cheaper not sure if those are free float though I stopped researching when I decided to go with the DD omega. Just thought I'd throw that out there in case you wanted to avoid the alternative.

If you have the right tools, uppers are extremely easy to work on, even easier than lowers. If you don't have the right tools, don't even bother.

That us exactly what my next question was going to be. Thanks for all the info guys. I'll start getting all the tools bought and start when I can. And I built the lower for this rifle so I should be ok working on the upper. I hope  . Haha

You'll need a 2-3lb hammer, bench vice, a hardened steel punch pin set these work nicely, Brownells FSB Template (it really does help), a torque wrench from Sears or Harbor Freight (I'm partial to Craftsman tools), THIS a Brownells (5) prong barrel nut wrench (the best I know of for sure), a 3/4" standard open wrench head (for removing the flash hider), an upper receiver action block from HERE, and whatever Allen wrenches your new FF rail requires for installing. I bought these tools to convert my Spikes M4LE into a Recce initially; and I've used all of them countless times now building my own rifles to MY exact liking and have saved me, my family and friends so much time and money. There are a lot of hack "gunsmiths" out there that will rob you and ruin your firearm. These tools are a great investment. |

If your using a two piece free float rail, or something similar, and a standard barrel nut you can simply dremel through your delta ring assembly shave down your front sight block with said dremel and install your rail.

Step one: find a hand guard you like that works with a standard nut.
Step two: Dremel with a cut off wheel. |

If you want you can buy a DD Omega rail. You don't need to remove the FSP to attach it to the rifle as it's a two piece rail. You'll just need the tool or a friend to depress the delta ring. It bolts into the D ring once you remove the old hand guards.

OP, you may want to check your home town forum for help. Might be a member near by with all the tools and works for a six pack.

Correct me if I'm wrong but the KAC RAS is not free floating like the OP is requesting.

Got it done today! This was a lot easier than I thought it was going to be. Went with the Daniel Defense 12" with FSB cutout. The only thing is I also had to punch the sling swivel. Have to get another that attaches to rail now but it looks and shoots better now. Thanks all again for the info.
