Product Description

The SCI-SIX is a centerfire rifle silencer designed for use on semiautomatic and automatic 5.56x45mm host weapons, with no barrel-length restrictions. The silencer mounts to the host firearm via a flash hider mount that uses left-hand threads to attach to the silencer body. It has a 1.64-inch primary diameter and measures 6.5 inches long with the mount installed. The main silencer body is constructed from 718 Inconel using additive manufacturing (DMLS 3D printing). The silencer weighs 17 ounces, and with the included flash hider mount, the total system weight is 19.6 ounces. The included mount adds 1.125 inches.
