| I have a Colt 6551 20" gov't weight barrel A2 sights etc. My question is would a Rock River National Match free float tube be compatible with this barrel? I have started practicing to shoot High Power Rifle and it is obvious that sling tension is giving me a wandering zero. I know it is the sling because I can make the wander go away by putting no tension on the sling. At the present time I can shoot no better than the rifle that I currently have, except for the sling tension issue. I figure I can always rebarrel this rifle at a later date as my skills improve to justify it or build a NM rifle from scratch. Either way the flee float tube will not go to waste. And no I do not have the money to buy a new $1000.00 rifle and yes, I have tried to sell this one to buy a NM with no luck. So this is just a stop gap measure. Will it work? |

The RRA NM Float tube is designed to work with heavier contour barrels than the one you have. I see no reason why you couldnt put one on your colt. You may need a different gas tube (not sure on that one). www.adcofirearms.com has the rra float tube for ~$100 i think. Also look into the White oak armament tube. www.whiteoakarmament.com (there are instructions for installation on this site under Articles=>tech) |

For my son, I have a NM FF tube on his WOA SPR upper. Its a real tack driver by the way. These type FF tubes come with their own gas tube. Yes, it will fit your barrel and you can do the work yourself. AR15.com has great tutorials with photos! Edit added: I forgot to say that I will be removing the NM FF tube in favor of a carbon fiber tube, simply to save weight. My son can shoot in the "F" class for high power. That is to say, I will be removing as soon as I can buy an upper receiver block. |
| The RR tube will work fine. If you are shooting highpower you'll want to consider at least a smaller aperature in your rear sight and a thinner front sight blade. Try an aperature of about .040 to .045 for starters. A lead weight for the butstock and handguard are a good idea too. Check out Ray-Vin for lead weights. That stuff should get you started without setting you back to much. When you get more money saved up get a complete rear sight with 1/4 x 1/4 or 1/2 x 1/2 adjustments, a 2 stage trigger and replace the barrel when it starts holding you back. Chances are you can shoot better than your rifle now and just don't know it. Your learning curve will be much faster with a rifle that is capable of extreme accuracy. |
