Phosphate vs 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 requires a lot of heat which can easily ruin that heat ...Advantages and benefits of Ni B, nickel boron, and nitro met, salt bath nitride on AR bolt carrier group, barrel, and gas tube assemblies. This is an inexpensive modern technology process to protect the surface of alloy steel against wear as well as corrosion. The traditional manganese phosphate process on mil spec bolt carrier groups […]

PSA is hitting me hard this week. Let’s discuss merits of Nitride vs. Phosphate for KISS handout rifles. Nitride MOE build kits for $299 or phosphate classic kits for $319. I am leaning towards the MOE just based on price. Then I am going to slap some carrying handles on, sight them in, and forget about them.MIL-SPEC is manganese phosphate, which requires oil to provide excellent corrosion resistance on the outside of the barrel. Mag phos typically has a matte grey finish. Nitride. Instead of adding material to the bore (like Chrome lining), Nitride treats the existing steel by imbuing nitrogen into the steel itself.Abstract. Gallium phosphide (GaP) is an indirect-bandgap semiconductor used widely in solid-state lighting. Despite numerous intriguing optical properties—including large χ(2) and χ(3 ...Quoted: "Melonite" is a proprietary version of nitride. There are MANY types/versions of nitride. Typically, "Melonite" or anything labeled as QPQ nitride will have a textured/satin look to it, where as the cheaper/quicker versions of nitride (without the polish/quench done after the first treatment) will have the glossy (almost blued) black ...IMO, the Black Nitride finish is the best bang for the buck of the black BCG finishes. It is a super hard finish that runs smooth and is both easy to clean and easy on the wallet. For a comparison of the top 3 black BCG finishes see our article The Best Black BCG Finish - Phosphate vs Nitride vs DLC .Chrome lining lines the bore of the barrel with chrome. Nitride is a process of hardening surfaces with a chemical and heat-based process. Criterion discusses the differences between nitride and chrome lining here. Phosphate is a coating applied to the exterior of a barrel to help prevent corrosion.Although phosphate holds lubricant better than nitride, I think I like the nitride more. The thing with an ar 15 BCG is that the contact surfaces are actually pretty small, the whole carrier isnt being drug through the upper, and phosphate isnt a very hard wearing finish. I personally prefer nitrided over phosphate, they clean up easier, however some nitride finishes are better than others where as phosphate finishes seem to a more consistent process. Always get nitrided. Nitriding converts and hardens the surface to improve durability and corrosion resistance. Phosphating is a coating that is meant to hold oil ...Yes absolutely worth it. If I were you I would get a LMT Enhanced BCG. If youre willing to spend $300. Otherwise I would stick with a reputable company for BCGs and just buy the black nitride BCGs. As long as it has a properly staked gas key and a good extractor and ejector, youll be set. Posted: 1/28/2014 7:20:15 AM EDT.A quality barrel can make or break a firearm. It impacts accuracy, durability, and corrosion resistance. Choosing a barrel that’s right for you can be challenging, so here are some of the main factors to consider. 1. Chrome lining vs. Nitride treatment: This is a debate that is ongoing: Which is better chrome lining, or […]Nitride processes also typically leave an external coating of black oxide as additional protection. So yes, nitride makes the surface harder, which phosphate does not. Nitride treats the bore of the barrel as well as the outside, which phosphate has no effect on.Phosphate barrels are typically less expensive than black nitride barrels. They also have good wear and corrosion resistance properties. However, they are not as …Re: nickel boron or black nitride BCG. Originally Posted by foxtrotx1. That would make sense. Phosphating is extremely porous. So the better it collects carbon, the better it holds on to lubricant. But something that doesn't hold carbon due to smoothness and has a nitride or NiB layer doesn't need as much lubricant. Hm.V vanadium V3+ vanadium(III) ion vanadous ion V5+ vanadium(V) ion ...

There's a reason metal cutting tools (end mills, boring bar inserts, etc) have nitride coatings instead of phosphate. There is very minimal wear surface on a bolt carier.Here is a guide on DLC vs. nitride coating to help you understand which is better for firearms. The Pros of Nitride. Nitride coating is the result of a heat process that creates a hard, nitrogen-based casing directly onto a surface. ... such as phosphate. The Cons of Nitride. Despite the benefits nitride coating offers, you should also know ...Geissele changed from mag phosphate aka parkerizing to black oxide. Nitride was always offered as an alternative. Secondly, this test is pretty useless. Nitride is on a whole other level as far as corrosion resistance. What people want to see is a comparison between mag phosphate and black oxide.Here’s a quick summary of the benefits of Melonite barrels: It is a sPSA PA-15 16" NITRIDE M4 CARBINE 5.56 NATO CLASSIC AR-15 RI Phosphate is a metal treatment to impart corrosion resistance. Still one of the better finishes on the market for someone making a "hard use" rifle. Melonite is a a metal treatment to impart corrosion resistance which also has the added benefit of being hard and "slick" very similar to chrome, which will allow the bore to last longer than that ...I also probably should have mentioned that the NiB BCG is a 9310 heat treated bolt, and the nitrided BCG is a shot peened 158 carpenter bolt. Nitride is pretty great, however I run NiB in all my rifles simply for the ease of cleaning. Also, Cryptic gang baby. I would try one of those out, the coating is unreal. Chrome lined vs Salt Bath Nitride vs non lined chromoly b 1,658. Phosphate is just basic parkerizing and will provide minimum corrosion resistance. It’s also porous and will make cleaning more difficult. Nitride is even harder and more corrosion resistant than chrome lining and produces sharper rifling which increase accuracy. Now, we must all fear evil men.Stainless steel gives better accuracy but at the cost of lower overall barrel life. That being said the average shooter doesn’t shoot enough or accurately enough to benefit from stainless steel. Nitride from a production standpoint is also easier to make and generally translates to cheaper barrels/uppers but exceptions do exist. 2 Likes. So what's the difference between phosphate and
