Features

This Franklin Armory lower, equipped with a binary trigger, is an ideal foundation for any rifle build. The forged 7075 T6 aluminum lower offers exceptional strength to handle the increased rate of fire from the binary trigger. It is an excellent starting point for a military M4-inspired carbine, as it comes with a Mil-Spec 30-round steel magazine, an A2 pistol grip, and a classic M4 carbine stock. The Type-III Hard Coat Black Anodized finish provides superior corrosion and wear resistance. Additionally, Franklin Armory has included a specialized tension screw to eliminate the wobble between the upper and lower receivers, ensuring a perfect fit with any upper receiver you choose.
