ATI Alpha MAXX Black Polymer Stripped Lower and Upper Receiver

The ATI Alpha MAXX Stripped Lower and Upper Receiver Combo gives AR-15 builders a complete matched foundation in a single package. Both the stripped lower and stripped upper are molded in black polymer and reinforced with patented over-molded metal inserts that strengthen the high-stress pressure points where standard polymer receivers typically flex.

Engineered to accept standard AR-15 / mil-spec components, this combo lets you choose your own trigger group, barrel, bolt carrier group, handguard, and furniture to configure either a rifle- or pistol-platform build. ATI's patented hammer and trigger pin design adds extra strength at the fire control interface for long-term reliability under repeated fire.

DISCLAIMER: Firearms and receivers are subject to state-specific shipping restrictions and must be transferred through a valid FFL dealer. Please visit our shipping restrictions page to review all applicable restrictions for your state. Subject to change.
