I'm a firm believer a little knowledge is a dangerous thing. I therefore defer to the Hide's knowledge on this. I received a much anticipated new barrel today, fluted and all. First glance, she's gorgeous but then I start to really look and notice a few things. I whipped out the bore scope and photographed what I thought were a few issues. Photos below.
I don't want to be "that" customer so I have a few questions about the state of this barrel. I want to bring up legitimate concerns (if there are any) and not waste any time on things I don't have the knowledge to judge and aren't actual problems.
First, are most new barrels fired in-house before shipping out? It does not appear the barrel has ever been mounted. The extension doesn't have any scratches or telltale signs it's used. But it appears there's a bit of carbon in the grooves of the rifling. I don't care either way, I just want to know what I'm looking at. There's a lot of leftover shavings and what not from the machining process so I'm thinking it wasn't ever used to fire a round. Chamber looks mint, untouched.
Second, I would assume the start of the rifling after the chamber needs to be uniform in distance. It appears the grooves start at varying distances, no rhyme or reason. Two next to one and other don't come all the way down to the chamber, most are right at the chamber, and there's a third that begins in the throat (think I'm using the right terminology there).
Third, I've always read the crown is the most important as it's the last thing the bullet sees. Well, this crown is a bit thorny and there's a small chunk missing at the very edge. Seems pretty rough the whole way around actually but that one spot is particularly glaring.
Fourth, there appears to be tooling chatter or something just before the gas port.
I bought this on Black Friday, made to order, expecting an 8-week delivery timeframe, but it showed up in essentially three weeks. Specs are HBAR, fluted, 223 wylde, only the barrel threading is non-standard for what most get for .223/5.56 so I can't see this being a previously installed/returned barrel.
Going to reach out about the crown regardless but would like input on everything else. Any info greatly appreciated.
Photos.
Let's start with various photos of the crown. My bore scope isn't the best so I apologize.
Gas port.
Dunno what caused this but there are semi-circular marks in certain parts of the barrel. Haven't cleaned it so maybe just oil residue or something.
Rifling in the throat.
Extension (which looks fine). I didn't take a super close look at the feed ramps but I didn't notice anything glaring whatsoever.
