81043 FF Ti - FFT Finished Titanium 2-Round Magazine Extension Tube for BLACK M4 Shotguns NOTES: Magazine spring and followers sold separately. The FFT / Wolff M4 full-length high power magazine spring is highly recommended for best results cycling loads. This part is an 'Air Force gray' and is NOT truly black.  TO BE CLEAR:  THIS TUBE IS NOT BLACK.  We do not manufacture any true black Titanium parts as you cannot get a good black look with the premium coating we apply to Titanium. THE FFT/WOLFF HIGH POWERED MAGAZINE SPRING IS ALWAYS RECOMMENDED WHEN ADDING MAGAZINE CAPACITY OVER 5 ROUNDS. For the Benelli M4 enthusiast who chooses not to go with a full magazine replacement tube, FFT offers the Titanium magazine extension tube. The FFT Titanium magazine extension tubes are manufactured with one-piece construction for strength and durability. The Titanium magazine extension tube is designed to replace the "limiter" that Benelli installs on every civilian M4 tactica
