Maxim has carried over M-Kore Technology to select small-caliber suppressors that benefited most from it. Serious 5.7x28mm shooters know that 5.7 rated silencers are hardly effective, both at sound reduction and durability. So they built a dedicated silencer just for that caliber. The MS:5.7 and MS:5.7K excel at heavy-duty usage and are at home on any 5.7x28mm firearm you own, even on full-auto.
