Description
There are plenty of .22 AR-style rifles out there, but only one of them wears the HK badge with Heckler & Koch's blessing. The HK416 .22 LR comes out of HK's partnership with Umarex of Germany, and it nails the look, weight, and control layout of the 416 carbine that earned its reputation with elite military units around the world. Aluminum upper and lower receivers give it a solid, legitimate feel in the hands, not the hollow plastic vibe you get from some rimfire lookalikes.
Built Like the 416 It's Modeled After
The details are what set this one apart. You get a functional dust cover, last round bolt hold open, a 90 degree safety selector, and a pistol grip with a storage compartment. The retractable stock adjusts to fit smaller frames or bulky range jackets, and the full length Picatinny top rail pairs with an M-LOK handguard so lights, lasers, and optics bolt on the same way they would on a centerfire carbine. Polymer flip-up sights come installed front and rear, adjustable and ready to go right out of the box.
A 16.1 Inch Threaded Barrel That Plays Nice with Suppressors
The barrel measures 16.1 inches with 1/2×28 threading at the muzzle, so a suppressor or your favorite muzzle device spins right on. And since .22 LR is one of the most enjoyable calibers to shoot suppressed, that threading is more than a nice-to-have. At around 5.7 pounds, the rifle is light enough for new shooters and all-day range sessions, with recoil that barely registers.
Why the HK416 Rimfire Makes Sense
Cheap ammo, familiar AR-pattern controls, and a 20+1 capacity add up to a rifle that pulls a lot of weight. Run it as a low-cost trainer alongside your centerfire rig, hand it to a first-timer learning the fundamentals, chase small game, or just burn through a brick of ammo on a Saturday. Owners consistently report it running reliably and shooting straight right out of the box, which is exactly what you want from something with HK's name on the side.

Frequently Asked Questions
Who makes the HK416 .22 LR? Is it a real HK?
It's manufactured by Umarex of Germany under an official license from Heckler & Koch, and it's the only HK-authorized 416 rimfire on the market. HK partnered directly with Umarex on the project, so the dimensions, controls, and styling stay true to the centerfire 416. It ships as a genuine HK-branded firearm, not a knockoff.
Is the HK416 .22 LR barrel threaded for a suppressor?
Yes, the 16.1 inch barrel is threaded 1/2×28, which is the standard thread pitch for most .22 caliber suppressors and muzzle devices. Just remove the factory muzzle device and your can threads right on. Shooting .22 LR suppressed is about as pleasant as range time gets.
How does the HK416 rimfire differ from the centerfire HK416?
The biggest mechanical difference is the action. The .22 LR version runs a blowback system instead of the gas piston setup on the centerfire rifle. Beyond that, it keeps the same general profile, retractable stock, flip-up sights, functional dust cover, and last round bolt hold open, which is why it works so well as a training companion.
Can I mount optics and accessories on this rifle?
Absolutely. The full length Picatinny top rail handles red dots, scopes, and magnifiers, while the M-LOK handguard takes lights, grips, and other accessories at multiple positions. The flip-up sights fold down out of the way or can be removed entirely once your optic is zeroed.
