I'm on the end of the barrels that many people will never see, chambering threading etc. I have used pretty much every barrel under the sun and some I wish never came in my door. I used to offer button rifled prefits that I machined in house along side Brux that I have been offering almost from the start. From my experience cut rifled barrels are usually always drilled straighter, almost never have any copper fouling, and last longer. Every button rifled company that I have dealt with usually had some sort of problems with barrels, some minor and some so bad I won't allow in my shop. I've had multiple customers order a bruxs barrels and then later tried something else and ended up ordering a brux to replace it. It's always worth the time to see what barrels are winning matches and holding records, some of the barrels out there will never be on those lists.
