I don't think the recoil is massively higher than other 7.62x51 rifles:
The noise can be reduced with some specific design changes that aren't a huge task at all.
With an improved stance and an experienced shooter the recoil is perfectly manageble, dare I say it- minimal?
Regarding high recoil of the firearm,I want to say something bout 7.62 NATO.
7.62 x 51mm NATO was designed in '50s in order to replace larger .30-06 springfield (in metric convention,7.62 x 63mm) round that had been servicing as standard issue battle rifle cartridge of USA since World War I.Their initial goal was to replace it with a cartridge that has at least SAME ballistic properties as itself if not more so in order to do that what they did was,they took empty casing of .30-06 and filled it with newer improved propellants and primers that significantly improved its performance,but also made it little heavier,so they downscaled it a little bit and fill up again with newer propellants to such amount that kept its ballistic properties (muzzle velocities,amount of pressure created by it etc.) to almost same (though,a little bit improved) levels.This simple 'jugaad' reduced weight of already heavier .30-06 as well as shortened it too,while also improved its performance a little bit then former one.Hence,a new cartridge was born designated as 7.62 x 51mm NATO.
So,basically we're firing an upgraded .30-06 cartridge from our OFB 7.62 that was already panned for having insane amount of recoil.
