I have an original Spikes Tactical Nickel Boron BCG from 2009 which has performed very well for me. I’ve shot thousands of rounds with it and had only one stove pipe jam. Although I still lubricate it regularly, I don’t clean it as frequently. However, the only issue I have with it is that it discolors over time and the bolt becomes rough in non-contact areas.
🟣 The discolouration of the Nickel Boron BCG is caused by a process called oxidation.
📌 Oxidation occurs when oxygen molecules in the air come into contact with the metal surface, forming an oxide layer on top of it. This causes the metal to become dull and its colour to darken over time.
☑️ To prevent oxidation and keep your BCG looking great, it’s important to regularly clean and lubricate it with a quality product designed specifically for Nickel Boron components. This will help to protect the metal from oxidation while also providing protection against rust and corrosion.
Hello. Can a Nickel Boron BCG affect the accuracy of a firearm?
The answer to this question is yes, a Nickel Boron BCG can affect the accuracy of a firearm.
🟦 This is because the Nickel Boron coating reduces friction between the bolt carrier group and the receiver, allowing for a smoother cycle and improved mechanical accuracy.
🟦 Additionally, because it does not require lubrication like other materials, such as steel or phosphate, there is less potential for debris or dust buildup which can decrease accuracy over time.
🟦 Finally, Nickel Boron BCGs have been shown to reduce felt recoil and muzzle rise due to its increased lubricity when compared to other material types.
I am confused about whether Nickel Boron BCG is good or bad. Some say there are advantages and disadvantages to using it. I am curious if applying NIb-X over regular nickel boron can eliminate the negatives. Also, if I add a bolt that is NP3 coated to the NIB-X Bolt Carrier, would it improve the performance of my rifle? I want to ensure that the BCG I am using will make my rifle run smoothly. Can you provide some clarity on this issue?
I own a niB bcg for my firearm and it has been a great experience for me so far. I have fired around 1300 rounds with it and to clean it, all I need is one wipe with a paper towel. I am amazed by its efficiency.
NiB coating can be inconsistent. While it’s fine if applied evenly, there may be issues if not. Therefore, I wouldn’t take the chance. On the other hand, phosphate-coated, chrome-lined carriers are perfectly fine. They hold lube extremely well and the claims that “carbon wipes right off NiB” are overrated. I’ve personally never done more than wipe off and relube my phosphate carriers and they run great. If you need a high-speed coating, np3 has actual material benefits and is not inconsistent.
As long as the coating was applied correctly, NiB bolt carrier groups should be of good quality.
TheB coating is not very good and is popular among beginners. If it was actually effective, more reputable manufacturers like LMT/KAC would be using it. However, as of now, they have not produced a NiB-coated BCG.
Can a Nickel Boron BCG fit in any AR-15?
🟡 Yes, a Nickel Boron BCG (Bolt Carrier Group) can fit in any AR-15 rifle. This is because the specifications of the AR-15 are standardized, and therefore any BCG designed for the platform should be able to work with it.
🟡 The Nickel Boron BCG is an upgrade from traditional chrome or phosphate coatings used on standard BCGs due to its ability to reduce friction and increase durability.
🟡 Its extreme lubricity allows it to cycle even more smoothly than other finishes, increasing the reliability of the AR-15 platform.
