As seen in 07/04 G&WLE, The KKF 'Milspec' A3 flash suppressor is an original design, and produced to bring 14 1/2" barrels out to 16+". It emulates the USGI A2 FS in looks, but is 1/2" longer. Its conical interior is 1 1/2" in length, is 22mm in diameter to interface with the USGI bayonet, and provides for those who prefer a more traditional look over the Phantom or Vortex with superior flash suppression. $90/perm. installed.
