Nefarious Arms barrel mandrel / upper receiver assembly / disassembly tool.

Seeing the need for a more comprehensive upper receiver tool Nefarious Arms re-engineered the barrel mandrel as we know it and made some significant improvements.

Compatible with HK416 and MR556 as well as Knights Armament SR-15 & SR-16 E3 barrel extensions.

In our opinion this is the best upper receiver tool on the market.
