This is the first official Heckler & Koch MP5 chambered in .22 LR. Authentic in looks, feel, and operation, this replica MP5 is engineered as a dedicated .22 rimfire rifle. It s built in Germany with a match grade precision barrel, metal receiver, MP5 standard forearm, and retractable stock. It also has a NAVY pistol grip as well as HK-style sights and an imitation 3-lug flash suppressor to maintain authenticity. The compensator is attached so that the 16.1 inch barrel extends the full length of the gun and compensator. The magazine is made of high-strength polymer and is designed with grips for the spring on both sides making it simple to load. A 20- and 10-round version of the magazine is available. Both are proportionate in size to the centerfire version's mag to maintain the authentic look of the 9mm MP5's magazine.

Very impressed with the build quality and it's weight for 22LR. No regrets, and is a hoot to shoot! The faux suppressor shroud finish scratches up easily with tough use (not surprised), but it's not a deal breaker. Highly recommended!

Absolutely no issues with this gun! Except the availability of the ammo... But the gun itself shoots anything I put in it. I've shot over 2000 Rounds so far with not a single malfunction. The gun is easy to take down and clean witch makes it that much more fun to shoot. Didn't have to use the adjustment bolt to shoot lower velocity ammo, it shot it with no issues. If you are on the fence about buying this gun I would definitely go for it! I did, and I'm happy I did.

Very high quality rifle. The H&K MP5 SD has performed flawlessly through over 800 rounds. Zero failures, even when using cheap 22LR ammo. It's very easy to clean and there is a really good video to show you how on the H&K website. Needs cleaning at about 250 rounds.

It gets a lot of attention at the range. I've made a lot of new friends by inviting the person in the bay next to me to shoot a few rounds. One guy thanked me three times. Really cool gun and a lot of fun. Extremely accurate. Unbelievable price. Bud's always gives great service. I had it 4 days after I ordered.

The H&K MP5 is a great rifle. I have not shot yet but have gone over it well and the rifle is great quality. Has a quality feel to it and quality parts. This rifle does not even compare to other .22 clones. The weight is very close to that of the true MP5. Got a 25 round mag. too! Overall great rifle, great price.

Very nice gun and shoots great too! Put about 150-200 rounds through it so far between to different days! No jams or anything! Very powerful sound and hits target accurate with little jerking motion in arm! Great gun for target shooting, small, game, or personal protection from intruders atleast 10 feet away. For men and women! Thanks!

Painless on-line ordering; prompt delivery (_ 5days); high-quality construction of this MP5SD variant. Has a weighty feel to it which IMHO, adds a nice balance. I fired 150 rds, CCI .22 LR HV, not a single issue. After a few rounds zeroing, I was putting consistent quarter-sized groups in the bullseye @ 15 meters. Very easy to breakdown and clean. Highly satisfied with Bud's service and the Walther H&K MP5; Keep up the good work!

Now if I could just find some ammo...

I received this item and have had it out to the range once... At 25 yards, all of my shots were impacting WAY too high, even with the rear sight clicked all the way down. Luckily, I noticed a replacement front sight post in the packaging, although the instruction manual makes no mention of it. The front post installed at the factory had a 1 marked on it and the replacement post has a 2 on it. The #2 post appears to be a good 1/16" taller than the #1, which should bring the bullet impact down, presumably into the proper area for 25 yard shooting. The sight post is simple to replace with just the included allen wrench (I recommend a dab of blue loctite). I haven't been able to re-test it, but if the bullet impact is properly lowered, I will be happy.

As noted in some other reviews, the gun is heavy, which gives it a substantial feel in my opinion. Also, the collapsible stock design may be uncomfortable, especially for larger adults, but it is an MP5 replica, so it is what it is. It would be nice if the stock had a bit of drop to it. HK also offers a fixed stock accessory that might be more comfortable for some people. A red dot on a riser would also probably make the shooting position much more comfortable.

If you are planning to mount any sort of optic, you will need to install the MP5 rail mount first. The OEM rail is $100 from HK... I'm sure it's very nice, but that is still expensive for a rimfire weapon. All of the knock-off rails that I have researched do not appear to fit the 22LR without modification... except a version made by MetalTac, which claims to fit the Walther/Umarex HK MP5 22LR. It can be purchsed from a very popular online retailer for about $30 with shipping. I have one on the way to test out.

Overall, this is not a precision benchrest rifle, but it is a very fun way to shoot lots of inexpensive ammo.
