Phosphate is a dull grey color and usually a little rougher. Nitride is usually black or blue and very smooth. One of nitrides positive attributes is that it is very slick and corrosion resistant. Old phosphate barrels can be a little slicker and shiny just from wear or exposure to lubricants.It basically boils down to a choice between a threaded muzzle or a target crown. Probably more than 95% of AR barrels these days are sold with muzzle threads. The threaded muzzle is cut a little narrower than the main barrel profile, and screw threads are cut into the last half-inch or so. On .223/5.56 mm it’s usually 1/2″ x 28 (1/2″ inch ...Unlike chromium and manganese phosphate, nitride doesn't "coat" the barrel. Instead, it penetrates the steel structure itself, attaching nitrogen atoms to the atoms in the steel. This process doesn't add any physical material to the rifling, so the barrel in question doesn't need to be specially fabricated to accommodate this treatment.You can nitride a 4140 barrel and it will hold up very well, often almost as long as a 4150 barrel that is chrome lined. But if the nitride barrel is 4150 and the phosphate barrel is 4140, then there is no debate at all, go with the 4150 steel that is also nitride treated.344 posts · Joined 2013. #2 · Sep 15, 2017. I bought a P224 barrel with the DLC (diamond like coating) description on the package. I think it's referring to the coating on the outside of the barrel. Initially, I thought that the coating on the barrel was scuffed up after a trip to the range. But, upon wiping it down, the coating looked brand new!Though it can be more expensive than a phosphate coating, black nitride has a shiny black aesthetic that offers superior performance, too. Nickel Boron Nickel boron-coated bolt carrier groups look like hard chrome BCGs, but they are actually produced through an electroless plating process that leaves a finish on the surface of the BCG that …The Stag 15 Classic Rifle is the high quality, durable, military proven M4 design rifle you've been looking for. Made to mil-spec standards, this rifle satisfies the need for a standard GI carbine. The Stag 15 M4 features a 5.56x45mm NATO chamber 16" 1/7 chrome lined barrel with our slimline free-float handguard, a mil-spec trigger guard, a six position buttstock, A2 birdcage flash hider and a ...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. Reality is unless you shoot thousands of rounds a year you wont outshoot the barrel.Jan 1, 2021 · Nitride is also much better than phosphate for the BCG. Phosphate is just too rough. Nitride has a very smooth almost polished finish that is much easier to clean and slides in the upper much easier. how ever fn is doing there mil spec is how i,d do it personally. there engineers are alot smarter than me.NEPA. Feb 3, 2022. #1. It seems like many well regarded companies are offering nitride/melonite bolts as a default these days. While it's certainly a more durable surface treatment than mil spec phosphate, I know there's a school of thought out there (& I'm sure @Constructorwill be along shortly to give voice to it) that it negatively impacts ...Posts. 1,661. 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.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. Been using a QPQ extractor for well over 2000 rounds suppressed on my DDM4 16.1" Middy.NiB offers more lubricity, but a properly made nitride carrier will still be superior to phosphate. I typically prefer nitride or hard chrome when given the option. If you're looking at NiB for the aesthetic, it is my understanding they stain quickly and won't stay looking shiny long. Coating doesn't matter.6.5 Grendel/6mm ARC Bolt Carrier Group, Complete - Black Nitride. $122.50 $175.00. Subscribe to back in stock. Out of stock. 9 Items. Shop for AR15 / M16 Bolt Carrier Groups from Aero Precision. Our BCGs are HPT/MPI and are the perfect firing mechanize for your next AR15 build.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.Noveske is one of my go-to's BTW. Lilja is hard to beat and Krieger is the titties. A chrome lined hammer forged barrel will be the toughest, last the longest and probably perform better than other chrome lined barrels mfg.'d other ways but I'm not sure who makes one for an AR10. Reactions:LilGucci. JMGlasgow.This BCG features a C158 bolt, 4340 extractors, and an S7 tool steOct 23, 2021. #1. Criterion 16" CORE Barr Phosphate has a rougher surface, it's good at trapping oil and I DO recommend you keep it well oiled. Nitride is slicker and has better rust resistance, im not sure if it's any better for wear but ya.. go nitirde if you can. NITRIDE!!!!! Go nitride, they are maybe $5 more and well worth it. I googled it & read mostly on forums but kinda ... DLC outperforms nitride by about the same amount that nitride outp Learn about the different types of barrels and materials for AR-15 rifles, including nitride and phosphate coatings.

Jun 27, 2023 · You have to use phosphate when you chrome-line a barrel. Phosphate goes on the outside, chrome on the inside. Nitride barrels are nitride all over. Can't use chrome on the inside with nitride on the outside...for whatever reason. As far as I know all DD barrels are chrome-lined.About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ...Phosphate is just fine, requires plenty of lube, but will last a long time. Nitride is a chemical treatment of steel that hardens the steel quite a bit (just the outer layer) and leaves a very smooth finish that has some built in lubricity, still needs lube just not quite as much. Stainless steel barrels are used for long range accuracy.Commisar2112 December 10, 2022, 1:15am 14. Phosphate was typically in the past also chrome lined. Its a parkerization process. But value oriented barrels phosphate exterior but no chrome. Nitride takes a very high temp and tempers the steel a bit more .It coats the inside and outside of the barrel. And since it is applied at such high heat, it ...

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. If it is finished in phosphate, it is finished with a phosphate treatment of the barrel.Regular and phosphate are the same, phosphate is the mil spec coating. Similarly, nitride and melonite are the same thing. Phosphate is just fine, requires plenty of lube, but will last a long time. Nitride is a chemical treatment of steel that hardens the steel quite a bit (just the outer layer) and leaves a very smooth finish that has some ...The nitride penetrates the steel structure by a few thousands of inches, forming alloying elements with chromium, molybdenum, and vanadium in barrel steel. As for the result, a barrel treated with nitride becomes extremely hard, translated with a Rockwell C hardness system between 62-72.…
