Wish it was melonite finished. I really like my CMMG 8.5 inch with melonite, and have several people that would love to have an upper like mine without the cost.

It IS "nitrided," so while it may not be coated by someone who paid for the privilege to use the term "Melonite," it does have that type of coating. What I'd like to know about it is who made it, and what type of nitrided coating it has, since both of those points make a difference. |

I have no doubt that the aero barrels which are tested per mil specs are better quality, what I shoudl have said is that is a remarkable price. Perhaps its too good to be true. |

The way I understand it nitride treatment is not the same as ferritic nitrocarburizing although it is a nitrocarburizing process, and can lead to some issues if the salt bath was done with the barrel extension in place. I know from several barrels done both ways that I have here the different finishes do not look the same. |

For that short of barrel though I would want a 1:7 instead of a 1:8. 1:7's stabilize subs better, which is the point of the .300 anyway (if used with a suppressor).

My experience with Ferritic Nitrocarburizing has been on using it to harden components such as idler shafts and other bearing surfaces. It puts a nice "candy shell" on the part and can be done a little more easily than traditional induction hardening, etc. It does give a nice dark gray or almost black finish if done well but can also have a slightly splotchy look depending on how the process was applied. |

This ^^^ I have no idea why manufacturers continue to insist on churning out short barrels with 1/8 twists. AAC switched the standard over to 1/7 for a reason...and that was a while ago at this point. So there is really no excuse. |

The 1/7 stabilizes very heavy subs better. Like 250 grain. 220s are fine with a 1/8. The really heavies are almost all cast as well, and many people wont shoot them. |

Well I ordered one of the 8.5" barrels and plan on shooting 203gr and 220gr subsonics through a suppressor should I be worried about baffle strikes?

Just ordered one myself and I don't really care about subsonics or how it looks. I'm pretty sure it's perfect for 125 grainers and the price is phenomenal compared to other 8.5" barrels I looked for.

I ordered one of the stainless and two of the nitride barrels. One for me and one is for my buddy and his brother's build. What has the typical shipping time been like out of PSA lately?

I ordered one for a pistol build. They already have my order ready; however, it will be an in-store pick-up, not being mailed. so IDK if that affects their shipping time. I have another order there to be shipped and it is still pending even though it is several days older.
I really don't care about great accuracy. I am building the gun for fun, and I will most likely be shooting 150 fmj. I do not have a suppressor, but I certainly will be wearing hearing pro!! |

I'm guessing (based solely on the price and the rare-for-a-cheap-barrel twist rate) that they may be same Bergara barrels being sold by Sportsmans Guide. Does anyone have any first hand knowledge of the SG barrels?

It looks like there is NO feedback on their site for those barrels...which I think is odd. |

I bought one, and it's already on the pistol. It looks fantastic, but now y'all have me worried about the chamber.
It'll be a week or two more before I'll have everything complete to shoot it and find out. I plan on trying the Fiocci 150gr and Rem 220 subs first. I will eventually just reload, so a short chamber doesn't bother me a whole lot. |

I will eventually just reload, so a short chamber doesn't bother me a whole lot. Let me quantify "way too short" for you. With my barrel, with a PTG "GO" (minimum chamber depth) gauge, the bolt would NOT get all the way through the barrel extension. The barrel would not accept a case and allow the bolt to close, PERIOD. Find a 300 Blackout case and see if you can chamber it AND close your bolt. It you can, you don't have a major problem. But if you can't.. |

Got mine delivered and it looks good overall. No idea on chamber yet. Not dimpled so I'm going with the YHM clamp on gas block. Finish is smooth overall. Pleased so far.

Mine showed up today, I ordered it last week, this is by far the fastest I have ever gotten anything from PSA. The barrel looks very good, I am actually pretty impressed with the fit and finish. The threads appear to be concentric when I mounted my suppressor, the chamber may be a little tight, but I wont know for sure until I get to put it together and test fire it. As long as it is capable of at least 2-3 moa at 100 yards it's a damn good deal for $80.

Hell, my CMMG 8.5" with the older 1/8 twist will do groups down to .7" with the Barnes black tips on a bench. I do not see much difference between these barrels unless the steel, or coating is different. But, it was mentioned earlier that the coatings apparently are the same. These are less than half what I paid for that CMMG.
