Griffin Armament HRT-556 Features The Griffin Armament HRT-556 is the shortest addition to the DUAL-LOK family of suppressors initially developed for elite HRT units before being released to commercial customers. The ECO-FLOW baffle stack carried over and tuned from Griffin s fourth generation Recce suppressors reduces back pressure and increases flow making the host firearm s operating system more reliable while delivering cleaner breathing air back to the operator. A patented low profile flash suppressing end cap works in conjunction with the baffle stack to further reduce flash signature despite the suppressor s compact size. Rated for full auto fire the HRT-556 is built to handle sustained use without sacrificing durability. The DUAL-LOK mounting system provides an accurate robust and wear free attachment method that has become a frequently requested feature among government customers. Constructed from stainless steel and Inconel and finished in Flat Dark Earth Cerakote the suppressor resists the extreme heat and corrosion generated during suppressed full auto fire. At 6.3 inches in length 1.5 inches in diameter and 16.5 ounces the HRT-556 adds minimal bulk or weight to the host weapon. The suppressor ships with a DUAL-LOK Minimalist Brake threaded 1/2x28 for 5.56mm use along with a branded Griffin pouch giving shooters a complete duty ready package for sale at GrabAGun.
