Randy R's Review of Rosco Manufacturing Bloodline .300 AAC Blackout Barrel
Long story short, back in January I ordered all of the parts to build a new AR Pistol. This is 7th or 8th AR that I have built, so I'm really not all that inexperienced. I decided to go with a Rosco barrel because of the reputation for quality. When the barrel arrived it came neatly packaged, and that's where the good ends. The barrel itself just looked off. The fit and finish wasn't great, and the markings weren't straight, but I decided to install the barrel anyway. I don't really care that much about the aesthetics of something that is covered up by the handguard as long as it functions. However, It didn't perform. Sure, it cycled reliably, but the accuracy was all over the place. On a good day I am about a 1 MOA shooter, on an off day 1.5-1.75 MOA. With this Rosco barrel at 50yds just trying to zero, I couldn't even put a group together. I also noticed that just the act of cambering and ejecting a cartridge would deform the casing and leave deep gouges in the bullet itself.
I reached out to Rosco, and was originally concerned that I had received a knock off barrel, their customer service actually got back to me in a timely manner, and I was informed that the barrel was a legitimate Rosco and the deformation and gouging was "Perfectly normal and wouldn't effect performance." Yeah right... but they told me they would replace the barrel for me anyway, but it would take 4-6 weeks. I agreed to that and sent them the barrel some time around the end of February. Granted, this is right before the Covid nonsense hit, so I gave them some leeway. around the end of April I emailed customer service again and was told the estimated shipping date would be May 29, so I waited until June and contacted them again and was told he would check and see. That was the last I have heard from them. It is now July and they will not respond to my emails. Maybe I am just a one off problem, Maybe I pissed off customer service? I do however think that five months is unacceptable. I feel like this issue will never be resolved, and have since cut my losses, ate the cost of the barrel, and ordered a replacement from Ballistic Advantage.
