Can ADCO contour a RRA 18" SS varmint weight barrel down to reduce weight? Not down to a Gov't Profile but close to the RRA SS NM barrel or maybe even little lighter? Some where between a HBAR and a M4?
What demisions in contouring are avalaible? Is there like a medium countouring available?
What is the wieght difference between the Varmint and HBAR with equal lengths?
