Bad Attitude Dept M4A1 Stripped AR-15 Lower Receiver - Stripped Lower

The Bad Attitude Department M4A1 Government Property Clone Stripped Lower reproduces the iconic M4A1 military markings through precision CNC engraving on a 7075-T6 forged blank — delivering the M4A1 look on a modern forged aluminum construction with an M4 government print FCG pocket and manufacturer markings beneath the trigger guard.

The Bad Attitude Department M4A1 Stripped Lower is a CNC-machined 7075-T6 forged AR-15 lower with hard coat anodizing, M4 specification FCG pocket, M4A1 Government Property clone markings via CNC engraving, 5.56MM caliber designation, manufacturer markings beneath the trigger guard, and lug pockets machined to the lower end of tolerance.

The FCG pocket is machined to current M4 government specification for full mil-spec trigger group compatibility. The tight lug pocket specification prioritizes a solid, rigid interface — uppers at the high end of their tolerance may require minor fitting. CNC engraving produces a visually distinct result from original M4A1 roll-marks.

Material: forged 7075-T6. Finish: hard coat anodized. FCG: M4 government print. Markings: M4A1 Government Property clone (CNC engraved). Caliber: 5.56MM. Lug pockets: lower tolerance.
