Foundingfathersar 15

Founding Fathers Armory manufactures precision AR-15 lower receivers using HAAS CNC milling machines—the only brand of CNC equipment built entirely in the USA. Every lower is machined from 100% US-sourced aluminum billet with exacting tolerances for fit, finish, and performance.

Their flagship AR-1791 lower receiver combines historical design elements with practical shooting features. The design includes:

• •Deep relief Liberty Bell engraving - honors the Founding Fathers and the architects of American freedom
• •Angular chevron magwell - a functional tribute to US Military rank insignia, recognizing those who've defended the Constitution

"Great men made it so. The sculpted, deep relief F2F Liberty Bell Logo is a conversation piece and constant reminder of our Founding Fathers' dedicated efforts."

Oversized Magwell Design Optimized for faster, smoother magazine changes. The tapered design creates completely smooth transitions while keeping magazines firmly seated. Compatible with MAGPUL G2, G3, MOE PMAG, ProMag, and most aftermarket polymer and metal magazines.

EZ Trigger Adjuster Included with every lower receiver. Works with standard Mil-Spec single-stage fire control groups to remove several millimeters of pre-travel, decrease trigger pull weight, and deliver a shorter, crisper trigger break for better accuracy.

Integrated Upper Tensioning Device Fully adjustable without disassembly. Delivers spring-loaded tension to eliminate upper-to-lower receiver rattle and play while ensuring proper bolt carrier and buffer tube alignment for better reliability and smoother cycling.

CQB Finger Grooves Increased magwell surface area includes milled finger grooves for secure support in close-quarter grip styles, delivering better weapon control in tight environments.

Oversized Trigger Guard Integrated design provides significant stability, rigidity, and protection for trigger and finger—with or without gloves.

Additional material beefs up critical areas: buffer tube tower, front pivot, takedown, magwell, and trigger guard. Result is a rigid, stable shooting platform that weighs just 9.4 oz.

The AR-1791 features MULTI-CAL marking, making it the perfect foundation for builds in 5.56/.223, 300 AAC Blackout, 22LR, 9mm, 45ACP, 6.8mm SPC, 6.5mm Grendel, and dozens of other calibers.

Each lower receiver undergoes a lengthy step finishing process: - Hand deburring - Tumbling to radius corners - Bead blasting for optimal surface prep - Type III Hardcoat or Cerakote finish application

Seven standard Cerakote colors available. Hundreds more custom colors offered at modest additional cost.

The AR-1791 uses standard .154" trigger/hammer and .250" pivot/takedown pins, ensuring compatibility with any standard AR-15 upper, fire control components, and accessories. Takedown detent and spring secured by set screw—includes shortened spring, set screw, and hex wrench.
