The thin blue line American flag with “Back the Blue” on the right magwell of a 7075-T6 forged 80% lower. A clear statement of support for law enforcement on a receiver that’s ready to finish — the kind of build a lot of officers put together for themselves or receive as a gift from their department or family.
Who This Is For
Active LEOs, retired officers, and civilians who want to show support. The thin blue line design reads cleanly on the black anodized surface. A natural pair with a solid black or dark gray build kit for a clean, professional-looking rifle.
Specs and Construction
Forged from 7075-T6 aluminum, machined to mil-spec tolerances, and black hard-coat anodized (Type III). Marked Model DT-15, Cal Multi, Made in U.S.A. Compatible with all standard AR-15 mil-spec components. The engraving sits on the right side of the magazine well — permanent and clean on the anodized surface.
Engraving Details
The design is laser engraved on the right side of the magazine well. Fire/Safe selector markings are not included. Optional left-side engraving adds a personal ID mark in the format DT + your order number — for your reference only, no records are kept or reported.
