A Lightweight, M4-Style Upper Receiver Designed for Varmint Hunting

Whether you're hunting for varmints or predators, having a rifle that can be fired quickly and maneuvered easily is a great hunting tool. The Franklin Armory F17-M4 is designed as a lightweight, handy carbine that's perfect for small varmints, thanks to the purpose-built design that allows shooters to make use of the hard-hitting .17 WSM.

Each Franklin Armory F17 upper receiver is built with a gas-piston operating system designed with the help of Osprey Defense, which is paired with a 4140 chrome-moly barrel complete with a salt-bath nitrided bore, chamber and external finish. This upper receiver is outfitted with a 16-inch, medium-contour barrel, which is finished with a threaded muzzle and flash hider. This design provides the lightweight, handy nature needed for fast-paced hunting, and it transforms any AR-15 into a great field carbine.

Other features found on the Franklin Armory F17 upper receiver include a forged A4-style upper made from 7075-T6 aluminum and treated with a black-anodized finish. The gun comes with a full Picatinny optics rail, as well as a forward assist that allows shooters to ensure their gun gets into battery. This upper receiver ships with the Franklin Armory F17 carbine buffer, which will function in either commercial or mil-spec buffer tubes. This system is not designed to work with A2-style buffers and springs. The company also warns that some aftermarket triggers may not provide the strength necessary for reliable ignition.
