Shock-absorbsion on firearms that are meant to be man-portable, and non-anti-tank, is simply mass, and either porting (cutting holes in the top of the barrel at the muzzle to let some of the propellant out and up) or using a muzzle-break (which does something similar, but is attached to the end of the muzzle).

A lot of what happens in the series is simply chalked up to 'rule of cool', and outright ignores physics to tell a more compelling story.

From the looks of the cartridges on Ruby's belt, they appear to be Nato 7.62mm rounds, which is fired by guns such as the venerable AK47, the modern SCAR-H, and the classic PSG-1.

So, from appearances, all the ammunition Ruby uses seems to be enhanced with Dust, and the Cross Clips are just a much higher dose than the unbranded magazines.
