Fortis AR-15 and AR-10 Switch & Night Rail Barrel Nut Wrench / Spanner Wrench
The barrel nut wrench works to tighten both the 556/308 Switch barrel nuts as well as the Night Rail. The Night Rail comes with a tool, but the Switch rails do not. You can use the standard 3 prong DPMS tool for the 308 and a standard AR-15 spanner wrench for the 556 Switch rail. Please follow proper Switch installation procedures.
