Many of us have dreamed of owning a H&K 416 however unfortunately most of us do not have $2800 in our pockets. Then of course enjoying an ammo emptying machine like a touted H&K 416 adds to the cost of ownership. Heckler and Koch heard these concerns and has joined forces with Umarex USA to deliver an HK branded/licensed .22LR replica of the HK 416 D145RS as well as MP5 A5, MP5 SD, and 416 Pistol. It adds up to a whole lot of fun at MSRP prices ranging from $475-559.

FIT, FINISH, & FEEL
Unfortunately many times .22LR reproductions fall short in providing the finish, feel and fit of the originals, however the HK416 D145RS is a very solid well built gun with excellent fit throughout. With the exception of the sights, pretty much everything on the gun that can be made of metal is. The cost reducing detail which bothered me were the aluminum non-captured front and rear take-down pins which are quality parts but could be lost more easily and plastic/metal sights.

FEATURES
From an appearance perspective, the .22LR HK 416 is a dead ringer for the real deal and it is pretty close functionally as well. Not to dash your hopes of bolting on an HK416 upper onto your existing AR15 lower, but as the HK 416 has proprietary internals and functioning different than an AR. The upper and lower receivers have been specifically designed to assure non-compatibility with standard AR receivers and trigger parts.

The intent by Umarex was to deliver a highly reliable .22LR version of the HK 416. From my understanding the stocks and grips can be swapped with any standard AR compatible parts, however the upper and lower internals are proprietary. On the outside the trigger feels like a really nice AR trigger but are drastically different internally than any standard AR and same goes for the bolt assembly. Part of the internals redesign was to reduce cleaning after firing those very dirty little .22LR rounds. To do this Umarex developed semi-sealed lower and upper internals on the receivers for less maintenance. The other two goals were to maximize accuracy and reliability which they did with a proprietary bolt design and spring which can be adjusted and tuned for more or less spring tension via a hex wrench. This maximizes reliability with faster or slower .22 rounds. To test this, I used Remington sub-sonic ammo which historically has not functioned well in my semi-autos and still enjoyed more neighbor friendly shooting and perfect reliability after I reduced the recoil spring tension. For most ammo, you will never have to tune the spring, however it is a great feature to be able to tune the reliability for hot or cooler velocity rounds.

FUNCTIONS


Where many will think the HK 416 missed blissful perfection was the non-functioning forward assist and bolt release when it seems from the location of both that they could have been engineered to work. In discussing this want vs. reality of many .22 AR conversions with two well known firearms designers (neither work for Umarex USA or H&K), they both coincidentally noted the same two potential safety issues. .22LR ammo is more sensitive to being mishandled than center fire ammo and by providing a way to slam the bolt forward aggressively either with a bolt release or forward assist on a misguided round, though rare, could cause a premature detonation or slam fire. Thus the reason most manufactures recommend a softer bolt/slide release method on .22s and why manufacturers may shy away from a working forward assists and bolt releases. The method of loading on the HK 416 D145RS whether the bolt is held open after a last shot or not is to insert a fresh loaded magazine, and charge a round by pulling back on the charging handle. Definitely not standard manual of arms, however I have been assured by two noted industry designers that this is a safer less legally fraught option.
The magazines for the HK 416 are made of high-strength polymer and are the best .22LR AR magazines I have had the pleasure of using. They are not compatible with more prevalent .22LR AR Black Dog magazines. They make reloading simple and fast with the thumb tabs on each side and include what feels like a constant force spring. The Magazines are available in 10, 20 and now 30 round versions. The 20 round magazines will most closely match the size of your standard AR magazines.


The trigger is very good with the feel of a two-stage trigger. There is a gradual take up and definite transition to the fairly crisp second stage. Throughout all the testing, I was very impressed with the reliability, perfect feeding, and firing of everything from standard velocity to CCI Stingers. I did have a couple failure to feeds after gunked up about the 450 round mark so plan on cleaning around that point.
ACCURACY
Like all the .22LR H&Ks and Colts offered by Umarex, the HK 416 is a dedicated .22 rimfire rifle which is engineered and built in Germany by Carl Walther. Accuracy is excellent with the match grade precision barrel and with inexpensive Winchester 333 no less, the HK 416 delivered this outstanding 30 round 25 yard group with stock sights. Once the front sight was tweaked, we were shooting dead on at 25 yards where the majority of shooting, plinking and training will occur with this rifle. My best 10-shot group was an amazing .5” group with open sights. This gun is a shooter.
FINAL THOUGHTS
There is a lot to love about this gun with my only relevant complaint being the need to tweak the sights for a 25 yards zero. This was a very fun gun to shoot and even with the HK 416 flavored style it is so close in weight and ergonomics to a real AR that it would be a logical choice for defense training and education. One of the most significant deficiencies with AR conversions has been accuracy and this is where the H&K 416 D145RS delivers with average groups in the sub 1” range at 25 yards and some of my best 10-shot groups under .5”. Frankly this German made Carl Walther .22LR shot so impressively and reliability it may rival my Tactical Solutions 10/22 with match grade barrel.

If you want to train a lot with an AR, .22LR versions like the Umarex HK 416 can pay for themselves very quickly in ammo costs and drastically increase your shooting time. Generally I pay around $.40 per round for cheap .223 for drills/training and I can pick up .22 ammo for around $.05 a round. Do the math and at the 1500 round or three 500-round brick mark you have paid for the rifle and the .22LR ammo. For me this is about two weeks of shooting. Not a bad deal and an easy inexpensive way to shoot more and spend less. The Umarex H&K 416 D145RS is definitely not just another “me too” AR .22 with “the look”. It delivers on look, fit, function and certainly accuracy and reliability, just remember to pick up plenty of extra magazines, because you will be shooting this gun a lot.

Awesome review. I do have some questions for you. At what range have you found this riffle to be the farthest and most accurate ? And do you have any reviews or posts on how to make the supplied sights more accurate? I hear they are a pain at first.
Thanks
I have really only shot out to the 50 yard line at this point, but the Umerax produced Colt and HK are both very nearly identically accurate as they use the same barrel and components. The stock sights are the weak point on the HK and take a little fiddling and tuning with a dremel tool to get to a 25 yard zero. Overall great AR15 22lr rimfire though.
Very helpful review. I just have one question for you. I haven't been able to find one in my area to look at, so I had my brother stop at Cabela's on his way home from school for break and he said that the magazine well is made of plastic. Is this true? It was my understanding that the receivers are both entirely metal.
Living in state of OK, have the HK 416 .22 LR HB pistol edition. Is it legal to add a forward vertical grip to the rail?
I would check on the legality with your local ATF. Generally adding a forward grip is considered converting a pistol to a short barreled rifle and requires NFA registration.
It not a sbr it a aow any other weapon
Needs tax stamp
Hi Folks. I've now had this rifle for a month and think that its awsome and i spent a long long time contemplating other fully functioning models out on the market. With regards to the bolt open. When porting arms for inspection at the range i use my right hand to pull back on the t-bar whilst inserting my left middle finger up the magazine houseing to engage the bolt open bar at the point the follower in the emtpy magazine would engage. I've got this movement very slick now and it's second nature. Of course you still have release the bolt by pulling on the t bar and not a nice functioning bolt relase but hey ho.
Great review, I’ve owned mine for a few months now and it’s been fun. My bro in law and I have had it at the range and it was great fun to shoot. I’ve bolted on just about everything that can be bolted on and my only complaint would be it has a screw on receiver extension which can’t accept mil spec stocks and mil spec pistol girps.
Has anyone found out what kind of aluminum its made of?
