This is the first official Heckler & Koch MP5 chambered in .22 LR.
HK recently decided to officially license the appearance of the MP5 to Carl Walther for production of a rimfire replica. Walther is now producing .22LR replica MP5 rifles at its facilities in Germany, and they are imported into the United States by Umarex. These rifles even carry an MP5 model name.
And Walther is well respected for it's weapons.
Regardless of who makes it, it's still called a compensator.
If you have one look right above the magazine well and see the H&K symbol.
