Protean Trivictus Pcar

I was struggling to get good accuracy from my Protean, and after success with the StryfeX barrel lug with pcar and a tight bore barrel after it, I replicated that setup for my Protean This uses the 14.0 T barrel as its base, and lengthens the amount of the tight bore by about double. The first half nearest the flywheels then has the 13mm Trivictus pcar from the Silly Spigot added and resized to 14mm I'm getting 3 out of 4 hits on a man sized target at 75 foot, using 1g darts, Fang RV's 42mm cage and bulldog wheels. I'm also blind… so that level of accuracy is good enough for me!
