Np3 vs nib Read our E-BCG White Paper HERE. Odd that is took that long to figure that out. Also, it's better to go NP3 than nickel boron. In my experience NiB coating tends to shed lubricant instead of letting it lay on the surface like Phosphate/Chrome Lined BCG's allow. I don't know the chemical difference, but NP3 is generally regarded as far more durable. NP3 coating has a very low coefficient of friction ~0. Nickel Boron (NiB) Why #3? Very durable, with excellent wear resistance and good lubricity (not as slick as NP3). It also provides high heat resistance. com Sep 24, 2024 · NP3 and DLC are the two most corrosion-resistant coatings, and both provide incredible protection against fouling. I'm considereing having my bolt/trunion parts in a prototype gun coated, just not sure with what, but both of those were on the list. More commercially available and less expensive than NP3 or DLC. Dec 23, 2013 · NP3 (and NP3+) are more for harsh environment corrosion resistance, while NiB is more for surface hardness and lubricity. All finishes except some weaker ones like phosphate or Nitride will stay virtually unchanged over the life of the carrier. That makes for extremely uniform surface coatings on parts with tight tolerances, like a trigger’s A well known Gas Piston AR Manufacturer recently stopped using NiB on their Bolts after years of touting how great NiB is. They stated the reason for the change was dimensional/tolerance issues. I've tried using regular cleaning methods with it, but the Ultrasonic was the easiest way along with a short soaking of Borete NiB is shiny and nice but tarnishes rapidly and is damaged more readily. Jan 30, 2023 · NP3+ has a low coefficient of friction, reducing wear and enhancing reliability. 1 even better than nickel boron 0. M16 Full Auto Style for increased mass and lock time. I’ve seen a few good apples, but typically, NiB BCGs have many issues with tolerances on every front. Nov 8, 2012 · Has anyone had XCR parts coated in NP3 or NiB? If so which parts, and have you had any problems? I'm planning to coat the [list type=decimal] Gas valve Gas tube Recoil spring guide Bolt carrier Bolt Op rod [/list] but I'm wary of doing the bolt and op rod. LANTAC E-BCG®, Enhanced Bolt Carrier Group. 8-2. Highly corrosion-resistant and easy to clean. Can discolor with heavy use but retains functional integrity. I've never seen pics of a chrome BC chipped though. May 9, 2019 · Nickel-boron (NiB) is an “electroless” gun coating, instead applied chemically. After reading it seems like the best would either be Nitride or Phosphate BCG’s. It is an electroless nickel-based finish for steel, stainless steel and aluminum alloys that co-deposits sub-micron particles of PTFE (polytetrafluoroethylene), otherwise known as Teflon™, with electroless nickel. The entire carrier assembly is NiB, Electroless Nickel Boron coated with the patented, advanced UCT EXO process All of the hand-wringing 'issues' of NiB apply to NP3 as well, as the process in making the parts is identical - just tweaks to the solution used. Nov 1, 2024 · No I did not. Like anything else, NiB has potential; it’s the manufacturers who give it a bad rap. . DLC is an incredibly durable coating with high lubricity. See full list on dailyshooting. if you EVER so much as wave a suppressor near one it turns black and loses it plating from carbon erosion Mar 6, 2017 · The NP3 and chemical process is done at an external vendor’s facility here in the USA. Jul 4, 2011 · Nickel Boron is supposed to be harder than chrome. Silky smooth, incredibly easy to clean and it just looks sexy. I am assuming the NiB is the shiny part of it, and it does trap a lot of carbon over time. Jul 21, 2015 · And I have Ares Armor phosphate, Nitride, NiB, and reduced friction BCGs. TiN is a golden coating that is really durable, doesn't tarnish too badly, and has good lubricity. A well known Gas Piston AR Manufacturer recently stopped using NiB on their Bolts after years of touting how great NiB is. I have an NIB carrier in my LWRC guns and let me tell you. It is also more corrosion-resistant and heat-resistant, making it Electroless Nickel plating (NiB, NP3) are hard, smooth, low coefficient of friction, corrosion resistant surfaces for the BCG or carrier alone. I have two, one is still waiting for it's new home to be built but the other is my absolute favorite to run. It performs similarly to DLC, albeit with slightly lower surface hardness. There's definitely a point of diminishing returns but the NP3 has significant durability advantages over NiB so if you're gonna go big go for the NP3. Our new BCG is precision machined from 8620 Steel with a shot peened bolt manufactured from Carpenter 158 or 9310 and Magnetically Particle Inspected. God Bless Eugene Stoner and Jim Sullivan's Masterpiece. The ejector should have a beveled edge and ideally be made out of S7 tool The SIONICS NP3 Coated Bolt Carrier Group: Better Looks, Better Performance The SIONICS NP3 Coated Bolt Carrier Group is not only aesthetically pleasing, but it also performs better than other types of coatings. Nickel boron is a hard, metallic coating that moves smoothly against other metals, and nickel Teflon is known for its durable, anti-corrosive properties. Jan 2, 2025 · NP3 is a proprietary finish offered by Robar Inc. The bolt should be made out of C158, but 9310 is acceptable from reputable manufacturers with high QC standards. That self-lubrication comes from the PTFE that is used in the coating. And to avoid all NiB parts. NP3 replaces the Boron of NiB with Teflon -softening the surface but reducing friction even more. 7-0. They have now switched to Phosphate Bolts. Nov 28, 2024 · 3. Very few broken in NiB BCG's come close to being as smooth as a Phosphate/Chrome Lined BCG when lubricated properly (which means generously lubricated). Jul 5, 2024 · Electroless Nickel PTFE (NP3) The science behind NP3 is a little complex, but basically, this coating is insanely smooth, strong, corrosion resistant, and self-lubricating. 0 according to different tests (LFW1 & ASTM D2717) (sourced from Robar). Oct 15, 2012 · I would appreciate feedback and opinions about guys that have either the NP3 or Nickel Boron(Fail Zero) finish on there Bolt Carrier Groups. This will add some lubricity and aid in the locking/unlocking of the bolt. If you want a cheap NiB boron carrier, just get the nitride instead. NP3 is a thin, impregnable coating that bonds to the host material, making it much more durable than other coatings. They still use NiB on their Carriers at this time. They're also the only BCG coatings that provide "dry lubricity," meaning they can function reliably without frequent oiling. NP3 has PTFE which is known as Teflon. All require Jul 5, 2019 · Looking at a lightweight BCG and the Nickle Boron is about $20 more than the Nitride coating. Is there a reason why NiB is much more popular than NP3 as a BCG coating? Thank you for your response. Titanium Nitride Jun 23, 2017 · NP3 or titanium nitride are the only two that actually work. Its actually a sign that you have a NIB-X instead of the less effective NIB and other lesser Nickel Boron Coating. Of the commonly used coatings (NP3+, Black Nitride, Armoloy, DLC), NP3+ is considered to have the highest lubricity and is the ideal coating for parts requiring low friction and good lubrication. The NiB is a step above the phosphate for cleaning, then the chrome, and then the Nitrides. Oct 29, 2024 · Pros: NP3 is regarded by most users as one of the best coatings for BCGs. Nickel Boron has a tendency to eventually flake. Im trying to find out which between the 2 coatings has the better protection, better lubrication properties, is the Stronger Coating (which holds up better on a BCG), Etc. I also have Anderson phosphate, SAA 'franken bolt', Tool Craft Nitride and Cryo BCGs, a YHM phosphate, and a Phase 5 chrome carrier with Nitride bolt. Unfortunately, the amount of issues often seen puts NiB in NP3 seems that it would be equal to or better than NiB due to its lower coefficient of friction and superior corrosion resistance. If you slept through science class, PTFE is Polytetrafluoroethylene – or more commonly known as Teflon. The only thing I have that uses NiB is my KNS Discarder. Also curious about TiN parts if you have any knowledge on those. Its use of Teflon ensures NP3 provides incredibly high natural lubricity and easy cleaning. In my opinion, yes. Jun 11, 2024 · NiB bolt carrier groups have given us the most problems from any other coating on this list. Imo it's not something I'd use when superior nickel-based coatings, like NiBX and NP3, exist. DLC is a PVD coating like TiN, but is super durable, super hard. You are supposed to be able to run NiB with no lube but I don't know that I would. In theory, electroless Nickel Boron is harder and more corrosion resistant than chrome electroplated. I do have an EXO coated Glock and can attest to the fact that NiB is very easy to clean. May 23, 2023 · This is another unique feature of NiB: enhanced permanent dry lubricity, that, like nitride coatings, is naturally slick and requires minimal liquid lubrication, keeping the bolt cleaner for longer. Nickel boron and nickel Teflon, also known as NiB-X coating and NP3 coating, are used to provide gun parts with a sharper look and feel, with each providing their own unique benefits. I've heard that chrome can chip, whereas I don't believe NiB can. I read all the mixed reviews of NiB so I avoided it. Also despite it being softer than NiB and thus more susceptible to wear, NP3 maintains its lubricity as it wears. If your new NIB-X Carrier comes in and stays bright as chrome I would be asking questions about whether you actually have the real NIB-X coating. I like the black Nitride but if the Boron is worth the coin A hard, slick coating like NP3, Chrome, DLC, or Nitride is preferred for the bolt.
