B&T sets a new standard for personal defense weapons with the BWC-9. Similar to the Magpul FMG-9, the BWC-9 can be folded into a compact rectangular shape, and swiftly deployed into a small carbine. Even though the BWC-9 represents a major advancement in firearms technology, the BWC-9 itself is not considered firearm. Instead, the BWC-9 is a frame or chassis that uses the fire control unit of a Sig Sauer P320 handgun (compatible with both carry and full sized units). Once the P320 Fire Control Unit is installed, the BWC-9 will be classified as a short barreled rifle and the proper Form 1 paperwork is required for ownership.

The BWC-9 unfolds in one swift movement after gently pressing back on the charging handle. Due to the geometry of the P320 Fire Control Unit, the BWC-9’s magazine will extend halfway out of the magazine-well while in the folded position, and will need to be fully inserted before the weapon is ready to fire. To fold the BWC-9, remove the magazine halfway, unlock and fold the magazine and grip into the forward position, then lift the “cheek piece” and the entire weapon will fold into itself. While in the folded position, the BWC-9 is remarkably compact, resembling a small briefcase or laptop case. The BWC-9 features a fixed carry handle for easy transportation, and also serves as a convenient way to hold the BWC-9 during the folding/unfolding process. In addition, the BWC-9 includes an Aimpoint ACRO P-2 Micro Red Dot Sight – an advanced optic that utilizes a fully-enclosed design to prevent debris from entering the optical channel/electronic components, hardened front and rear glass lenses to better protect the internals, and is rated to withstand heavy recoil.

  • Instantly deploys in one swift movement

NOTE: The installation of a Sig Sauer P320 Fire Control Unit into the BWC-9 will result in the manufacture of a Short Barreled Rifle (SBR). ALL NFA REGULATIONS APPLY.
