Two Los Angeles Sheriff’s Deputies who were wounded in an ambush-style shooting have filed a lawsuit against Polymer80, claiming that the weapon used in the shooting “was originally purchased as a kit in California from either Polymer80 or one of Polymer80’s third-party distributors, who sold it without performing a background check.”

The deputies were shot last year in their patrol car, which was parked outside a bus station in Compton.

The suspect was arrested three days later. Ballistics tests allegedly linked his handgun with the attack on the deputies.

He was legally prohibited from purchasing or possessing a firearm.

“The shooter was able to commit the ambush shooting of the deputies because Polymer80’s deliberate and reckless acts created a direct and secondary market that foreseeably provided prohibited persons like the shooter with easy access to un-serialized ghost guns assembled from kits and purchased without any background check,” the lawsuit states.
