Franklin Armory Libertas Stripped Lower Features The Franklin Armory Libertas lower receiver is machined from 7075-T6 aluminum a material prized for its strength to weight ratio in AR pattern builds. The black hard coat Type III anodized finish provides excellent corrosion resistance while giving the receiver a durable surface that holds up to repeated handling and use. A flared magazine well speeds up magazine changes by guiding the magazine into place more easily than a standard straight-walled well. Ambidextrous push button QD sling mounts are built directly into the receiver giving shooters flexible sling attachment options regardless of handedness. A specialized tension screw is engineered into the design to eliminate upper and lower receiver play resulting in a tighter more consistent fit between the two halves. An integral cold weather trigger guard provides extra room for gloved fingers during cold weather shooting while serrated memory index points and a textured front grip area improve control and feel during offhand shooting. Designed to accept most aftermarket AR-15 mil-spec parts the Libertas gives builders broad compatibility with standard components already on the market. For anyone building a dedicated AR platform rifle the Franklin Armory Libertas offers a premium highly functional billet lower receiver.
