One of my factory assembled bushy uppers (20" govt profile) has a little over 12k rounds through it, still shoots just fine but I was likely going to replace the barrel anyway in the coming months and give the old one to a friend for a chop job. Should I wait until the accuracy really drops off, or go ahead and replace it? When I originally purchased the upper from bushy I went ahead and ordered 2 extra barrels just to have on hand so money isn't really an issue. |

Most people replace their barrels when the accuracy is no longer acceptable for their intended purpose. I don't think I'll ever change the chrome-lined barrel on my Colt LE6920; I'll leave that one for my grandson (and I'm 26). However, if I were a High Master in the NRA highpower game, I'd start ditching the barrel once I notice CONSISTENTLY that shots that should have been 10s are 9s. For a Krieger Stainless steel, non-chrome lined barrel that's somewhere between 6000-8000 rounds, I believe. |

A thread titled "Typical Barrel Life/Accuracy Problems" was around recently. Type in barrel life on the search function. A fellow from UK had a sectioned 1:9 barrel that had seen no FA use. It had 5500 rounds on it when it wouldn't shoot 855. The first 1.5" of the rifling were completely gone. Good pic. I shoot mostly FA so would likely not do so well. OTOH, minute of abandoned car is good enough for shoots. Sam |
