I am looking at the specs for this flash hider and it says the overall length is 2.1" So if I bought this and pin/weld it to a 13.9" barrel it would make this 16" length. I know doing simple math 13.9 + 2.16 = 16.06 but I want to know if it would for sure be 16-inches and make it a legal rifle. Thanks.
MATT · Jun 2, 2025AT3 Support Team — Yes, pinning and welding the Dead Air Xeno Flash Hider to your 13.9" barrel will make your barrel length legally 16 inches or more, provided the installation is done properly by a qualified gunsmith.
