Description
The HK416 .22 LR magazine from Heckler & Koch is a factory replacement and spare feeding solution for owners of the HK416 rimfire rifle. Built in polymer, it keeps weight down and resists the kind of corrosion that metal magazines can develop when exposed to the residue that .22 LR ammunition tends to leave behind. Because rimfire cartridges headspace differently than centerfire rounds, dedicated rimfire magazines like this one are engineered specifically for the geometry of the .22 LR case — drop-in compatibility with a generic AR-pattern magazine is not something you can count on, which is why sourcing a factory H&K unit matters if you want reliable feeding.
A 20-round capacity puts this in a practical middle ground for shooters who want enough rounds for a sustained range session without the added length of a higher-capacity stick interfering with shooting from a rest or prone position. The magazine’s dimensions mirror those of standard HK416 furniture, so the handling characteristics and manual of arms stay consistent with what HK416 owners already know. Having a spare on hand also means training sessions don’t get interrupted waiting for a single magazine to be refilled — a straightforward consideration that becomes obvious the first time you’re running drills.
Part number 51000200 is the correct factory reference for this magazine, which makes cross-referencing compatibility with your specific HK416 rimfire platform straightforward before purchasing.
