Description
The HK416 22LR Rifle 20 Round is HK’s licensed HK416 rimfire (HK part 81000401) in 22 LR, packaged with one 20-round magazine for longer strings at the range.
HK416 22LR Rifle 20 Round Overview
HK specifies aluminum upper and lower receivers, a 16.1-inch barrel threaded 1/2×28, a rail interface system with M-LOK slots and a Mil-Std 1913 top rail, a retractable stock, a pistol grip with a storage compartment, adjustable flip-up sights, a 90-degree manual safety, a functional dust cover and a last-round bolt hold-open. HK lists the weight at about 5.7 pounds without a magazine, a height of 10.8 inches and a width of 2.6 inches.
Who Makes the Rimfire HK416
HK licenses its rimfire replicas to Carl Walther in Germany, which builds them as straight-blowback 22 LR rifles. They copy the look, controls and handling of the military rifle, but internally they are simple rimfire semi-autos, so the parts and magazines are specific to the 22 LR model.
The 20-Round Package
A 20-round magazine means fewer reloads during plinking and lets a new shooter run a full drill without stopping. It also looks closer to the military rifle than the short 10-rounder. The longer magazine can touch the bench when shooting from a rest, so a bipod or bag under the rail helps. HK also sells 10- and 30-round magazines.
Rail and Furniture
The aluminum receivers give the rifle a solid, AR-like feel rather than the toy feel of some rimfire replicas. The retractable stock adjusts length of pull for smaller shooters, which is one reason it works well as a family rifle. The flip-up sights fold away for a red dot, and the storage compartment in the grip holds spare batteries for an optic.
Ammunition and Reliability
22 LR remains the least expensive way to practice rifle handling skills, though prices vary with lots and brands. Blowback rimfires like this one generally run best with high-velocity 36- to 40-grain round-nose loads; bulk subsonic and standard-velocity ammunition may not cycle reliably, and dirty, waxy rounds build fouling in the chamber. Rimfire primers also produce the occasional dud, which is a normal part of shooting 22 LR.
Honest Caveats
The muzzle is threaded 1/2×28, but a suppressor is an NFA item that requires an approved ATF Form 4 and must be legal where you live. Magazines are specific to the rimfire HK416 and cost more than common rimfire magazines. This is a licensed replica, not an HK-built rifle, so it shares no major parts with a centerfire G36 or HK416, and resale reflects its rimfire role.
State Laws and Ownership
Pennsylvania does not require a permit to buy or own this rifle, and buyers 18 and older can purchase it through a dealer. Other states are stricter: some cap magazine capacity, some regulate features such as pistol grips, adjustable stocks, flash hiders or threaded barrels, and a few restrict how a long gun may be transported. The included 20-round magazine is not legal in states with a 10- or 15-round limit, so this package cannot ship to those buyers as configured. Check your state and local rules before ordering, and ask your receiving dealer about any restrictions where you live.
