The Franklin Armory BFSIII M4-BLR features a precision-forged 7075-T6 aluminum lower receiver with a hard coat Type III anodized black coating for enhanced durability and corrosion resistance. It includes a specialized tension screw that eliminates any upper/lower play for a secure and tight fit. Equipped with the FRANKLIN ARMORY® AR-ESSENTIALS™ trigger, the lower receiver is designed for smooth, responsive performance.
The lower features a standard A2 pistol grip for reliable handling and comfort during use. The included stainless steel magazine with Marlube finish holds 30 rounds of 5.56 NATO ammunition and is available in 10/20 or 10/30 round configurations for restricted states. The M4-design stock is reinforced with a six position collapsible capability, multiple rear sling mounts, and an angled heel for easier transition, built on an aluminum carbine length receiver extension.
The Franklin Armory BFSIII M4-BLR is an ideal platform for AR-platform builds, offering a complete lower receiver package ready to pair with your AR upper. Whether you’re building a tactical rifle, designated marksman rifle, or varmint platform, this multi-caliber lower receiver provides the precision-engineered foundation that Franklin Armory is known for.
