Roller-delayed blowback, such as those in the CETME/HK pattern guns, is not synonymous with harsh recoil. The MP5 is one of the lightest recoiling, smoothest running 9mm shoulder fired guns out there. The 5.56 guns are a pussycat.
The Cetme/HK style roller delayed guns in 7.62 NATO can vary a bit in terms of felt recoil. I have shot some contract manufacture 91s that were vicious, and I have shot some that were smooth as a 5.56 gun. This is dependent on the timing of the unlocking of the bolt. The timing can be altered by trying different locking pieces. It has been my experience that heaspacing can also contribute to the felt recoil of these guns. The headspace can be altered with different sized rollers that can be put into the bolt head. The collapsable A3 stock can increase the perception of recoil because it isn't as comfy on your face. In 9mm and 5.56, this isn't an issue for me, but it is more noticeable on the 7.62 NATO guns.
HK style roller delayed blowback guns are also very versatile. You can choose from a number of handguards. There are several stocks available, including ones with AR type tubes. There are various grip frames available (steel, polymer, ambidextrous), including one that also uses AR pistol grips and trigger guards. Reason I mention this is that most people don't realize how versatile these guns really are in terms of modularity.
