Franklin Armory BFSIII Equipped LIBERTAS BLR Complete AR15 Lower Receiver - Black | Installed BSFIII Trigger | B5 SOPMOD Stock Installed

50 Remaining

Extremely high quality 7075-TG Aluminum billet lower receiver made by Franklin Armory with their excellent Binary Firing System III trigger installed. 


Franklin Armory®'s custom designed billet lowers are now available! This design incorporates integrated ambidextrous, anti-rotational Quick Detach sling mounts. On the magwell, forward of the trigger is a textured Memory Index Point for safely resting the trigger finger when not ready to fire.

The magazine well is also enlarged and beveled to facilitate quicker magazine changes. The integral trigger guard is over-sized to allow room for larger hands or gloves. The front of the magazine well is also textured to allow it to be used as a grip for forward support. These Built Lower Receivers come with a B5 SOPMOD stock installed. This allows the customer to install whatever stock they prefer without paying for a generic one that they may likely remove anyway.
