Gun enthusiasts are a particular breed. Some are anti-government Second Amendment nuts, clinging to their full-metal security blankets for comfort in a terrifying world. Others are target-shooters, or collectors, or people who just have an affinity for weapons as machines of purpose. That last at least, is pretty understandable — these people usually fall more under the auspices of automotive gearheads than 2A nutjobs. And, as one of these, I’ll go on record as saying that the new R.I.P. round from G2 Research is by far the coolest thing I’ve seen all week.
