Advanced Armament Corporation (AAC) have developed a new ultra high-end suppressor called the Ti-RANT. It weights about 1 oz less than their Evolution 9mm suppressor while offering greater sound reduction. This is achieved by using titanium and titanium alloys, hence the name Ti-RANT.
The specs are:
Weight: 8.6 OZ (244gm)
Length: 7.9” (201mm)
Diameter: 1.38” (35mm)
Finish: GunKote, T3 HARD COAT& SCARMOR
Sound Reduction: 35-38dB
The business end of the Ti-RANT
Of course the high-end construction and technology comes at a price. AAC will be selling it for $1195 shipped. That is about $300 more than the Evo 9.
