I am doing a custom build and trying to figure out if I can use a particular chassis. It simply states that this chassis
  • Compatible with aftermarket barrel profiles up to a Medium Palma (0.920" dia. 5.50" forward of the breech). My dilema is I have chosen a 26" Criterion VARMINT contour barrel but have no idea of the diameter of this barrel 5.50 inches from the breach. Does anyone in the peanut gallery know if this barrel will fit this chassis or "Am I trying to fit a square peg in a round hole?"
