Caliburn V4 Scar Muzzle

This is a different style of muzzle break that introduces splines along the inside of the part to give the dart some spin on it to increase the accuracy of your shots. I have uploaded a variety of pitch degrees in the files below. I have only tested the file labeled V4.2 Scar 20 pitch and it has given me some very good shots and have been for the most part very very straight.

This design has been specifically made around the worker half length darts and has not jammed or failed to leave the barrel compared to some other darts I have tested.

There are six different files that have different pitches to the inner splines that affect the spin of the dart. **I HAVE ONLY TESTED V4.2 Scar 20**, This pitch works really really well. I am waiting on printing the other 5 when I get the chance.

I predict that as the pitches get higher, the velocity at which the dart leaves the barrel will be greatly reduced but it may give you great accuracy. I think somewhere in the range of 14-18 wil
