The NCStar AR-15/M4 Gunsmithing Tool Kit (NCStar part no. TGSARKB) is not a knife; it is a purpose-built tool roll that puts many of the AR-15/M4-specific tools an owner needs to build up a rifle or carbine in one organized package. NCStar designed the kit to cover assembly work starting from a stripped lower receiver, along with the tasks involved in mounting all kinds of aftermarket accessories to customize a rifle or carbine to a shooter’s specific needs. Every tool in the kit is organized on a large black cleaning mat that rolls up with the tools secured inside, keeping a full AR-15 toolkit compact enough for a range bag or workbench drawer.
