While E.R. Shaw has earned its reputation producing custom and OEM barrels for many major American firearm brands, the company’s new semi-custom Mk. X bolt-action rifle line merits attention. Featuring blueprinted actions, lapped bolts and precision-cut chambers, accuracy is literally built into these rifles. With over 80 different chamberings to choose from and more options than you could ever dream of, the Mk. X makes crafting a rig to your specs, tastes and budget easier than ever. Learn more about it in the video embedded above, hosted by Executive Editor Jon Draper. MSRP: $1,630; shawcustombarrels.com.
