Description
Shooters who want to run the HK416 platform without the cost of centerfire ammunition will find this factory H&K magazine a straightforward solution. It is designed specifically for the HK416 rimfire rifle, so fit and feed geometry match the host gun’s receiver rather than relying on the tolerances of a third-party part.
The body is polymer, which keeps weight down and allows H&K to integrate a translucent window so you can read remaining rounds at a glance without dropping the magazine. That cutout is a practical advantage during a range session when you are tracking round count across multiple magazines. Loading is assisted by a thumb tab on the follower, which takes the effort out of seating the last few rounds — a detail that matters more with rimfire ammunition, where case rims can stack unevenly under spring pressure if the follower doesn’t guide them cleanly.
Ten-round capacity suits ranges and jurisdictions where standard-capacity magazines are restricted, and it keeps the magazine profile short enough to clear most shooting benches and barricades without the extension of a higher-capacity stick. Because this is a factory H&K part built for the 416/G36 rimfire platform, it drops free cleanly on release and locks back the bolt on the last round, maintaining the manual-of-arms that makes the HK416 rimfire a useful practice tool for shooters already familiar with the centerfire version.
