Distinguish yourself with a rifle as unique as you are with the bold, unique profile &
features of the AR-1791 Lower Receiver from Founding Fathers Armory!
Choose from Graphite Black, Tungsten, Burnt Bronze, Coyote Tan, MAGPUL FDE or ODG CERAKOTE
Stress Relieved, Aerospace Grade Solid Aluminum Billet, sourced exclusively from US Suppliers is precision machined to exacting dimensions with tolerances of +/- 0.005" using the latest 5 Axis CNC Machine technology for superb fit, finish & performance.
Iconic & Functional
Distinguish yourself & your rifle with the AR-1791's Aggressive Angular Chevron Magwell design reminiscent of rank insignias proudly worn by so many in defense of our great nation. In addition to looking totally cool & unique, it also provides a positive indexing point for both forward & rearward magazine changes assuring quick, hassle free reloads under pressure in low or no light.
Internally Tapered Magwell
Designed for faster, smoother magazine changes, the 1791's oversize magwell is beveled & taper milled with no interior ridges or pockets to snag magazines. Optimized for all generations of MAGPUL™ Magazines.
Natural Support Side CQB Grip
The increased surface area of the forward magwell includes milled finger grooves for comfortably secure support hand CQB, close-in or high magwell grip styles resulting in better weapon control in close quarter environments. This natural grip is so comfortable & secure you will wonder how you ever managed without it!
EZ Trigger Adjuster
Included with every AR-1791 Lower Receiver, the EZ Trigger Adjuster replaces the standard pistol grip bolt. When used in conjunction with Mil-Spec single stage fire control groups (you know, the inexpensive LPK triggers 98% of us use...), the EZ Trigger Adjuster can remove several millimeters of trigger pre-travel (or"slop"), decrease trigger pull weight & provide a shorter, crisper, smoother trigger break resulting in better accuracy & tighter groups.
Upper Tensioning Device
No more lost Accuwedges! The Integrated Spring Loaded Upper Tensioning Device is fully adjustable without disassembly & applies tension to the upper receiver, ensuring a tighter fit or "Lockup" between upper & lower receivers. This eliminates rattle & play between receivers, while also assuring proper alignment of the bolt carrier & buffer tube for better reliability, less noise & smoother cycling.
Oversize Trigger Guard
The integrated oversize (Winter) trigger guard provides significant additional stability, rigidity & protection for both trigger & finger with or without gloves.
Mil-Spec Parts Compatibility
Mil-Spec standard .154" Trigger/Hammer & .250" Pivot/Takedown Pins assure compatibility with standard AR-15 uppers, fire control components & accessories.
Beefed up where it counts
Optimized using the latest CAD/CAM software, additional material has been added to reinforce & strengthens critical areas such as the buffer tube tower, front pivot bosses & trigger guard to provide increased strength & rigidity resulting in an incredibly robust & stable shooting platform while still weighing in at a skinny 9.4 Oz
Finished in Style
Each AR-1791 Lower endures a lengthy 4 step finishing process of hand deburring, tumbling to radius corners, bead blasting to provide the perfect pre-plate surface before the final Type III Black Anodized Hardcoat or Cerakote finish is applied.
Pocket Size US Constitution
Every Founding Fathers Armory product includes a free pocket size copy of the US Constitution from the National Center for Constitutional Studies.

Founding Fathers Armory is the AMERICAN dream in action! I left a 19 year career in the corporate world and decided I could do better with my IRA than Wall Street. So I cleaned out the IRA, bought a CNC mill and started Founding Fathers Armory.
I believe in AMERICAN MANUFACTURING! I only buy raw materials and supplies made in the USA. I mill my parts on AMERICAN made CNC Milling Machines from HAAS Automation Inc. and I include a free pocket size copy of the US Constitution with every product I sell.
