SLINGHAMMER Precision Rifling Muzzle 12mm

Muzzle compatible to DONDIPPER's SLINGHAMMER design https://cults3d.com/:952560

FOR 12mm ONLY!

Experimental muzzle with rifling. A friend and me had precision problems with the original design, so we came up with a muzzle with internal rifling. For both of us, the design improved the precision significantly. However, the material thickness in the area of the fixation screws is at it's limit, the muzzle might break if too much force is applied with leverage. Use at your own risk.
