Anyone have a range report on the cheap m4 nitride barrels that radical fireams and redbarn have for sale? From what I understand they are the same barrels.  I just got one from radical and it looks good as far as outward appearance goes.  I plan on using it on a dissipator build just waiting on all my parts to show up.

The barrels you are talking about are excellent. I have shot mine about a 1000rds thru it with no problems. Accuracy is on par with any other quality CMV barrel.
