With a decent strength and a cyber/military armo gyromount, you can get rid of the recoil (remember it can't take accessories, but mods are still fair game). That said, a AVC 7.62 can take [High Velocity, Firing Change: Small (FA), Extended Ammo: Drum, Personalized Grip] and then have a Gas Vent 3, Top mounted Smartlink, shockpad and Gryomount. It costs a lot more, but can do pretty much the same thing with a 100 rnd. drum and an RC of 11. High Strength will let some of the Gyromount compensation roll over to negate movement penalties.
This is all because the High Velocity mod is horribly written and doesn't really fit with all the weapons that already have it. In all reality, the modification should grant 3 points of RC but prevent any barrel/underbarrel mods, or none of the base weapons with it should have the restrictions. After all, if Ares R&D can't manage it, a runner in the shadows with some armorer tools shouldn't be able to.
