This is a “no modification required” power tuning barrel for the VKS launcher. The keys to success on this barrel are what we kept the same as well as what we changed.
What we kept:
-Steel Detent system for extra strength and reliability.
-Barrel stabilizing O-ring for centering the barrel.
-Push and turn installation system as original.
-D Shaped breech to accommodate shaped projectile.
What we changed:
-Length shortened to 12” with Lapco Style Thread Protector
-Bore sized to .685 for better match with Grimburg Jul and CRB Hybrid ball.
-Smooth bore to better accommodate round ball projectile.
