Delivering true drop-in compatibility with full-size MP5-pattern platforms, the Victrix lower requires no fitting, gunsmithing, or modification for installation. It arrives fully assembled with a pre-installed fire control group featuring a smooth 3.5 lb Nickel Boron (NiB) coated single-stage trigger, a 7075 aerospace aluminum slip trip, and ambidextrous 3-position rotary safety controls. Outfitted out of the box with the premium Forward Controls Design (FCD) GSA A1 grip, the Victrix lower transforms your roller-delayed platform into an ultra-reliable, high-performance system.
