Umarex HK MP5
Umarex HK MP5 22LR
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 25- 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 MP5s magazine. The estimated retail price for the MP5 A5 is $475.
Operation
The .22 caliber HK MP5 A5 operates on a blowback system. The bolt holds open when the magazine empties. Its front sight is adjustable for elevation and comes with interchangeable posts. The rear sight is adjustable for windage and elevation. Its safety switch rotates in the same manner as the 9 mm MP5. (Credit HKRimfire)
This was a rifle we had been looking forward to getting for some time. When we picked it up the only MP5 22LR clones we could find in the local gun stores was the GSG version. GSG had lost a lawsuit with HK and was forced to change the look of their HK clone, thus it no longer looked like an HK. Also the ones we were finding were the plastic lightweight versions and to be honest they felt like toys. GSG does make a conversion kit to change the look back to an HK. The kits go for anywhere from $20 to $50. We will get more into that next month when we pick up the GSG 522 PK.
Happily we found the HK version at the Crossroads of the West gun show in Delmar. $550 was a pretty heavy price tag for a 22 but we couldn’t resist.
We picked up our HK 22LR and headed straight to the range. Unlike most of the guns in the RGR armory we didn’t change or modify a single thing on the SD version but we did add a forend light from Laser Devices on the A5 version.
We had read many reviews of the gun and a lot of them talked about the gun jamming or being finicky with ammo like the Sig Mosquito. For whatever reason we really didn’t have that problem. Sure we had two FTF and one jam in the first 200 rounds we fired. But some guns do require a break-in period. Since then this gun has fired over 1,000 rounds and with the exception of the first 200 we have never had another FTF or jam. And we use the cheap ammo from Wal Mart. No high velocity 22lr ammo, no CCI, just the cheap Winchester 550 box.
This gun looks and feels pretty much like a real HK and it should. It is licensed by HK, built in Germany by Walther and then imported in the US by Umarex. So please everyone stop saying it’s made by Umarex, it’s made by Walther. And if you don’t know who they are…well you should.
One of the best parts of having a 22LR in the state of California is they do not fall under the “Assault Weapon” ban. The law is written for “centerfire” rifles…not rimfire. So because of that there is no bullet button or any evil features ban. Magazine capacity is still 10 rounds in good ‘ol CA. The only rifle I have ever seen with a higher capacity is a 14 round, tube fed, Marlin 22LR.
We have the Umarex HK MP5SD version and the A5 versions. Both come with a fake suppressor to cover the long 16” barrel and a collapsible stock.
Every time we let someone shoot this for the first time they fall in love with it and run out to buy one, and who can blame them. With the current economy shooting 22LR keeps the sport alive for some of us. There’s nothing more fun than spending hours in the desert shooting and it not costing $500, with this rifle we can spend all day shooting for $20 and have fun doing it.
Have fun shooting!
