Franklin Armory Libertas Stripped Lower Receiver Features The Franklin Armory Libertas stripped lower receiver is machined from 7075-T6 aluminum a material chosen for its high strength to weight ratio and resistance to flexing under hard use. The hard coat Type III anodized OD Green finish adds a durable corrosion resistant surface that stands up to field conditions while giving the build a distinctive look beyond standard black. A specialized tension screw eliminates the upper and lower receiver play that can plague standard AR-15 builds tightening up the fit for a more solid consistent feel. The integral cold weather trigger guard is enlarged to accommodate gloved fingers keeping the rifle usable in winter hunting or cold weather duty conditions. A flared magazine well speeds up magazine changes under time pressure guiding magazines into place faster during range sessions or competition. Ambidextrous push button QD sling mounts let shooters set up a sling on either side of the receiver without additional hardware and the serrated memory index point gives the trigger finger a consistent reference point along the receiver. A textured front area improves offhand grip control when shooting without a forward rest. Compatible with most aftermarket AR-15 milspec parts the Libertas gives builders a dependable well finished starting point for a custom rifle project.
