Everything the Defender is, lighter.
The Defender LW (Light Weight) gets its weight savings from the Ballistic Advantage Performance Series Hanson-profile barrel. The Hanson isn’t a pencil barrel; it’s more of a competition cut. Choose 13.9″ or 14.5″ of barrel. Paired with the MFT Minimalist stock, the LW comes in at just 5 lb 11 oz with the 14.5″ barrel.
Order it as an SBR on an ATF Form 4, or pinned & welded to 16″ as a standard rifle.
