Frequently shooters find that they have issues with wear to specific components in their firearm systems. Frequently fire control groups will show a lot of wear, and this can be an issue no matter what kind of shooter you are. One of the best ways to deal with excess wear in the action parts of a fire control group is to use parts with next-generation coatings that are less susceptible to wear from friction and repeated use. When you’re ready to change your AR-15 fire control group to one that takes advantage of next-generation coatings, Wing Tactical has an awesome option. The WMD Guns NiB-X Fire Control Group features a proprietary Nickel Boron coating that makes this an excellent choice for those who are interested in a Nickel Boron Fire Control Group.

Why Choose a Nickel Boron Fire Control Group?

When you choose an AR fire control group you want a good value for your money, that means you want parts that will give a long service life under the stress and friction of repeated use. An excellent way to assure that you will get the best possible service life from your AR-15 Fire Control Group is to choose one that takes advantage of the properties of next-generation coating like Nickel Boron. Nickle Boron fire control groups like WMD’s NiB-X AR Fire Control Group. The inherent lubricity of WMD’s NiB-X nickel boron treatment allows free movement of the components without excess friction or the issues that are frequently caused by an accumulation of dirt and debris that becomes attracted to the additional lubricants that some components require in order to function smoothly.

NiB-X Components Are Wear Resistant

WMD’s NiB-X nickel boron treatment is harder and more resistant to wear than other nickel boron fire control groups. NiB-X coating will outlast competitors’ treatments, providing your NiB-X fire control group a longer, more reliable service life.

  • NiB-X trigger

    Posted by Seth Jones on 5th Apr 2021

    Easy to order and arrived quickly. Fit and finish is excellent. No issues installing in my Anderson lower. Finish is slick, but trigger doesn't slip when firing. Haven't measured trigger pull weight, but it's definitely lighter than my friends standard milspec trigger and just feels way smoother/shorter/crisp. Funny part was installing this slippery thing under spring pressure :D

  • Worth every cent nice finish and way nicer then standard coatings
