Buying Info Videos

Radical Firearms has built their reputation on gun parts manufactured completely in house by a work force that is made up largely of veterans who know what works. What started as a hobby became a small shop that gradually kept acquiring more CNC and other machinery to create their own parts to their own tolerances as they built platforms for discerning customers with specific needs. Now Radical Firearms is a Title II NFA manufacturer with a complete (and still growing) selection of gun parts, AR15 uppers, and much more. Their fully tooled and operational gunsmithing facility produces components economically for everyone from military and law enforcement professionals to 3Gun participants. Radical Firearms stands by their gear with a Lifetime Warranty for as long as you own it. For background information about your purchase, browse our informative GearExpert Blogs or the collection of articles linked at the bottom of the page. Remember, our product experts have decades of hands-on experience and are a free resource we provide, so contact them for ideas via email, chat or phone. Buy from OpticsPlanet.com for great service and great gear at great prices. Plus free shipping on orders over $49.image
