The Diligent Defense DTF-STi shortens the Big Bore DTF for a handier package in the field. The 6.75″ OAL and ~9.2 oz titanium construction keep length and weight off your muzzle without giving up strong sound reduction. With HUB 1-3/8×24 compatibility, it pairs easily with your preferred mount ecosystem, and it’s set up for 8.6 BLK & 338 ARC while being capable of suppressing everything up to .338 Lapua.
