(AP) — A former U.S. Army officer who operated a business in Portland selling military-grade weapons parts and accessories pleaded guilty Friday to arms export violations and mishandling classified documents. Regulations require people selling weapons items that are on a U.S. munitions list to obtain a license from the U.S. Department of State. Prosecutors say he generated more than $12,000 by selling and exporting 287 restricted items to buyers in 34 different foreign countries during a 15-month period — including rifle scopes, grips that facilitate faster shooting, and levers that improve reloading.
