May 27, 2023 · 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 . Hexagonal boron nitride (h-BN), 31 which belongs to a hexagonal system, is a white block or powder, has a layered structure similar to the graphene lattice constant and similar characteristics, and is sometimes referred to as 'white graphene'. 32-34 h-BN is a lattice alternately arranged by B atoms and N atoms in a two-dimensional plane ...Bolt-carrier groups above, from left, represent Nickel Boron, phosphate (Palmetto State Armory), Robar NP3, black nitride and chrome-plate (Daniel Defense).Advances in gun coating technology can ...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.Posts: 2,119. Nitrade vs. Nickel Boron BCG. Holiday sale. $80 for the Nitrade or $90 for the Nickel. I need a few and the $10 is immaterial if there's an actual performance difference. My biggest complaint of the AR is that it fouls the bolt badly and is prone to jamming due to the gas design. If I can improve the performance for the extra $10 ...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.Phosphate provides better results than nitride and BCM is a better brand than toolcraft. So the answer is pretty easy.Nitride - Not a coating, but a surface treatment of the metal. Very hard, and usually easily cleaned. Impossible to flake off. ... but not as hard or durable as chrome or nitride. Can discolor, and in rare cases can flake off. Manganese Phosphate - Much cheaper than the other options, the army did this in the 60s because they didn't want to ...Nov 27, 2019 · Hardness levels produced by gas, plasma, or Liquid Nitriding are similar, ranging from between 600-1200 HV (60-70+ HRC), hard chrome plating is around 70 HRC. It boils down to personal preference. Nitrided is definitely easier to clean, but a parked BCG is far from difficult to clean. Phosphate vs. Nitride Barrels: Which is Better? A phosphate barrel with a chrome-lined interior. One of the advantages of nitride finishes is that you apply them to …The Black Nitride coating vastly increases the hardness of the steel, prevents corrosion, is highly resistant to wear, will not flake (it's not a coating, it's a bond), and has increased lubricity when compared to a phosphate-finished BCG. The Bolt Carrier Group is the heart of your rifle, and if you want to upgrade the functionality of ...36) vanadium (V) nitride V 3 N 5 37) strontium acetate Sr(C 2 H 3 O 2) 2 38) molybdenum sulfate Mo(SO 4) 3 39) platinum (II) sulfide PtS 40) ammonium sulfate (NH 4) 2 SO 4 Ionic/Covalent Compound Naming Solutions 1) Na 2 CO 3 sodium carbonate 2) P 2 O 5 diphosphorus pentoxide 3) NH 3 ammonia 4) FeSO 4 iron (II) sulfate 5) SiO 2 silicon …Barrel Finish: Phosphate Chrome Lining: Extra - thick chrome lined including chamber Muzzle Thread: 1/2-28 Chamber: 5.56 NATO Twist Rate: 1 in 7" ... With all being equal except for chrome vs nitride barrel I guess I can settle on the nitride barrel. Thank you for your help sir. Posted: 7/1/2020 6:38:21 PM EDT ...In general, "hardened" surfaces have a lower coefficient of friction, which aids in functioning and other features. Platings would include nickel boron, along with chrome, plain nickel, gold ...I have the choice between two 10.5" pistol build kits: one with a .223 wylde phosphate heavy profile barrel, another with a .556 NATO nitride A…

Looking to pickup a complete Palmetto State Armory (PSA) complete 10.5" upper. They offer it in both Nitride and Phosphate finish - which one should I get? The phosphate ones are about $20-25 more expensive than Nitride. I know both finishes are solid, but always thought Nitride was "better".What’s the difference between Phosphate and Nitride? Been thinking about getting a PSA 10.5 upper for a Mk18/CQBRish Block I build. When trying to compare the uppers I see …Quoted: Nitride is a harder and slicker finish than phosphate. Nitride will wear better, last longer, and have less friction than phosphate. 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.Firearm Discussion and Resources from AR-15, AK-47, Handguns and more!
