I got my first AR15 2 years ago (after 40+ years of trigger time behind the M1 rifle) to shoot in XTC matches. I've been contemplating installing a NM float tube and handguards on it lately to try and improve my scores. I finally bit the bullet and ordered a CLE NM service rifle float tube kit for it a couple of weeks ago. I had it installed today. As soon as I get the chance, I'll give you a range report, be it good, bad or indifferent. I hope it will be an improvement and not all done for naught.
