KWA GBB KMP9 SMG – Just Cause AIrsoft

SKU N/A Categories ,




The KWA KMP9 series is based on a small lightweight 9mm submachine gun and features a integrated folding stock and a moulded fore grip to provide a stable shooting platform for the user.

The KMP9R features a bottom accessory rail in place of the moulded fore grip allowing for attachment of accessories. Both models have an accessory side rail as well as a top accessory rail for optics and other weapon attachments. KWA has also produced a CQB bolt assembly that can easily be swapped to reduce the exit velocity of the weapon for indoor CQB environments.

The KWA KMP9 series provides a large amount of firepower in a small compact tactical package.
