V3 inspired v2 Rifling Mandrel - Wire Based Progressive Twist (50-10) 4.5in 8.82mm ID Barrel

this is basically the same mandrel of the Ivan’s V2 ECM set. but there have been 2 pin’s added so it can be used upside down like the with the V3 ECM set from ImmortalRevolt.

but be aware that the V2 from Ivan and V3 from ImmortalRevolt have different tooling. so it’s best to not mix them. the differences are small so be careful.

but I liked the concept of removing potential air bubbels in the proses. by filling it up with water that needs to be pushed up. so I have added the other parts that are needed to do this upside down with Ivan’s Rifling Mandrel - Wire Based Progressive Twist (50-10) 4.5in 8.82mm ID Barrel
