| After looking at and researching a few different models of ARs I've decided on the Colt LE6920. When I do get it I plan on changing the handguard to a RRA quad half rail. What do I need to do to do this conversion? |

ARMY TM 9-1005-319-10
http://www.cgunworks.com/Chatahoochee_Gun_Works/Media/AR-15.pdf I'd save and studying up on a copy of the TM for the M16A2/3/4 and M4/A1 Rifles and Carbines; and go through it. It'll cover everything to maintain, disassemble, and reassemble one. Which we share commonality with, in our AR-15's, except for the fire control group. |

What do I need to do to do this conversion? This is not what you want to hear but swapping in that RRA rail would be more trouble than it's worth. 1. Heavy...usually end users want to get rid of those because of their weight. 2. Uses proprietary barrel nut...you would need all the tools/skills to mount and dismount a barrel 3. You would also have to un-pin your FSB to get the RRA on....not an easy task if you have never done it I would recommend one of the several good drop-in rails. This would be the most painless way to upgrade your handguard. The USGI barrel nut and FSB remain in place. You may want to start another thread asking for drop-in recommendations. |
| Thankyou for your input. The reason I was going to go this route was because I've read that free floating the barrel/handguard improves accuracy, allowing the barrel to flex when fired, allowing for a more consistent shot. Is the improvement in accuracy enough of a difference to make it worth the pain in the @#$ as you are saying? |

Why buy twice? Buy a rifle that is set up the way you want in the first place. There is nothing magical about COLT despite what the fan boys say and in fact, my two Colts are my least favorite ARs, complete rattle buckets and the accuracy is not as good as my home builds, but in fairness I use a better quality barrel than Colt can or should since they are using chrome lined barrels built for longevity, not accuracy.
Point is, IMO it makes no since to buy a rifle then start pulling things off and replacing when more than likely you can buy a rifle set up the way you want it from a smaller manufacturer, unless the prancing pony means more to you than anything else. Rainier Arms, LaRue, Bravo Company, Spikes Tactical, good Lord the list is endless and IMO any of them will make you a rifle the way you want it and it will surpass the Colt in almost if not all areas and you not only pay less for the initial base rifle but you only pay once, getting the rifle you want without a lot of parts needing to be swapped out. |

It certainly doesn't hurt to have a floating barrel, but most handguards require some major disassembly and special tools. An easier option would be to find a handguard that uses the GI barrel nut you already have. In that case, you would only need to cut off the delta ring, the spring under it, and the handguard cap (does depend on which rail you choose though). |

I thought about this and you make a good point. I looked at RRA last night and I'm thinking about ordering a complete upper and lower separate. Will I need to do anything at all to put the two together or will they just "snap" together without and modifications? |

My vote would be either the Troy 2 piece or Midwest Industries 2 piece Free Floating rails. That way you don't have to remove the FSB. You can just use a dremel and cut off the delta ring and spring (many youtube vids on this). Both utilize the stock barrel nut, so no special tools required for install. Here are links to the rails
Troy MRF-CX rail MI Extended Carbine rail |

And with that huge amount of work which takes all of 30 seconds you save yourself 15%! That is hard to pass up. Just be sure NOT to order the lower and upper at the same time or they will hit you with the 15% Excise Tax. They have to be on two different orders. Or you can buy just the lower and shop around for the upper you want, they do not have to be the same maker because all AR-15 uppers and lowers are swappable, or should be anyway and one of them would have to be seriously out of spec for them not to swap around. |

I plan on ordering separate mainly because it will be easier on my wallet. I'm looking for a complete upper with a free float rail or tube with a low profile gas block or a flipup front sight. |
