Machined,
not molded.

Every chassis starts as a solid block of aluminum and is precisely machined to tolerances of 0.02 mm, for maximum rigidity and durability. The QD sling mount is cut directly into the frame, so there's nothing to bolt on and nothing to work loose.

"Machining quality is as good as it looks. Everything locked up tight with zero rattle, and the spare mag holder is smarter than it sounds."

"Still no bigger than a full-size pistol, but way more controllable. The QD mount being machined in is the detail that sold me."
