For a reproduction of an antique gun, such as the 1858 Remington, I think either finish would look inappropriate. Neither finish is necessary for ease of cleaning, longevity, or any other reason. I'm not into modern in-line rifles, but I doubt there is reason to go with either stainless or nitride coating.From all the research of done on chrome vs nitride for AR barrels, it really seemed like if you were not using full auto, Chrome doesn't add that much benefit, and seems like it would be completely unnecessary in a handgun. ... The P226 MK-25 barrel is phosphate coated (parkerized) on the outside, and chrome lined in the chamber and riffled ...Nitride is a surface treatment that hardens and protects steel barrels from wear and corrosion. Learn how nitride differs from phosphate, chrome-lining and other coatings, …its a hard coating, and is superior to black nitride in surface wear resistance. black nitride hardens the metal to a substantial depth and makes for pretty good wear resistance, and really good long term wear., I prefer black nitride, with the understanding that my gun will have some visible long term wear marks, like a well used glock slide.That was my original plan. It’s about $100 or so to thread the barrel, not including shipping. For $155 I could get a phosphate 20”a2 barrel from Delton or JSE surplus. Problem with that is F marked fsb.

Wonder how it holds up compared to the Sig factory nitride or phosphate finishes.My WMD NiB-X has had zero extraction issues. Perhaps the phosphate bolt in nitride carriers is that the temperature to do QPQ properly is very close to that which could soften the temper on the bolt. That could be dangerous.

A Nickel Boron BCG with its slick surface will clean up quite a bit easier and faster than a standard BCG with a phosphate finish. The rough phosphate tends to hold the dirt and grime while the Nickel Boron doesn't seem to as much. You will still get carbon build up on the tail of the bolt, but that's going to ...Phosphate has more texture, which holds oil but produces its own friction. Nitride might on average be less hard than phosphate depending on treatment quality, but basically never in a way that would matter to you. The amount of time the difference will ever matter to you is close to zero.Barrel: 4150V Chrome-moly steel pencil barrel, chambered in 5.56 NATO, with a 1:7 twist, M4 barrel extension, and a mid-length gas system.

Compare the benefits and drawbacks of each finish and choose the best option for your needs.I would avoid the Lantac M-Spec because it's nitride. Nitride does not add any thickness to the carrier and regularly leads to a BCG that is not as efficient as its phosphate, chrome, and NP3 counterparts. And absolutely avoid any BCG that offers a nitride BCG with a 9310 bolt. 9310 is already difficult to heat treat and the nitriding process ...Wolfspeed (WOLF) Could Start to Run With Pack...WOLF Wolfspeed (WOLF) is a developer of wide bandgap semiconductors that adopt silicon carbide and gallium nitride technologies.

Nitride all the way. 1 to 7 is a good twist rate if you want to shoot the heavier 77 grain ammo and works well with the green tips. 1/8 is a little better for the 55 grain stuff.In theory, nitriding will be more accurate than chrome and 416 will be more accurate than 4150. The 6.5C barrel was 416 nitrided. Stainless cant be chrome lined. 4150 will be more durable in extreme firing schedules, but not as accurate because it does not take shape as easily as the softer 416.Nitride, Melonite and phosphate are all surface treatments - not coatings. If it says the barrel is nitride finished, it means the barrel is finished with a nitride treatment - and all that entails.

And since it is applied at such high heat, it ...The QPQ coating offers several benefits. First of all, it improves the properties mentioned above. Also, for many industries and applications, it is essential to increase corrosion resistance. So, quench polish quench becomes a very helpful treatment for them. Some of the most relevant advantages of applying QPQ treatment include: Improved ... We would like to show you a description here but the site wo Except Nitride has changed things. It used to be chrome lined vs phosphate or blued. Nitride actually hardens the metal without the thickness variances of chrome lined. Many folks say it is better because of that.
