Why Radical Firearms

Every barrel, upper, and rifle leaving Stafford is built on equipment Radical Firearms owns — not outsourced. Button-rifled CMV barrels, nitride-treated bolts, forged 7075-T6 receivers, and Melonite-coated gas blocks. The same parts we run on our own rifles, sold direct without the price creep of a three-tier distribution chain.

Ships Nationwide

This product ships direct from our Texas facility to any FFL dealer in all 50 states. NFA items (suppressors, SBRs) require Form 4 processing through the transferring dealer.
