When you operate an AR-15 there are dozens of small parts that take a lot of abuse. Some parts, like fire controls, safety selectors, and magazine catches, are activated every time you use with your firearm. You might not think much of how those small parts endure constant use and friction, but if there’s a problem you’re going to know it right away. One way to avoid having problems is to choose components that feature next-generation coatings that extend service life, resist wear, and require less maintenance. If you’re looking for a magazine catch with those qualities, Wing Tactical is proud to offer the WMD Guns NiB-X Magazine Catch. This drop-in Nickel Boron AR15 Magazine Catch replaces your standard magazine catch directly, no adjustments needed.

Why a Nickel Boron AR15 Magazine Catch?

It might sound like a flavor of the month product, a trendy choice with little to back up the need for such a product, but there are some really good reasons to opt for selectors, catches and controls with next-generation coatings. When you choose a WMD NiB-X Magazine Catch over a Mil-Spec coated catch, you get smoother operation and less concern over maintenance. WMD’s NiB-X is a proprietary nickel boron coating process that leaves behind a self-lubricating surface that wears 40% longer than some traditional Mil-Spec coatings. Less friction makes for a longer wearing part and easy operation. NiB-X coating on a magazine catch makes it easy to operate and less likely to bind up with dirt since the lubricious nature of the special nickel boron coating stays cleaner longer. That’s a bonus when you’re working in varying conditions and need to be able to rely on the easy, predictable operation of your AR-15.
