In the heart of its design, the Volquartsen IF-5 has an I-fluted stainless steel barrel which not only offers weight reduction and greater service area for cooling but holds a dramatic appearance. The I-fluted also features a CNC-machined stainless steel receiver, integral picatinny rail, TG2000 trigger guard, tuned extractor, and a CNC-machined bolt with a black nitride titanium round firing pin.
