Wheaton Arms is the brainchild of Robbie Wheaton, an experienced gunsmith and three-gun competitor. The Wheaton Arms Sentinel ISR (Interdiction of Squirrels Rifle?) is a five-pound Ruger 10-22 with a match barrel, and an integral mono-core sound suppressor installed. The suppressor can be removed for maintenance, and the rifle comes with a 3-1/2# trigger pull.
Derek got on the list to have one of these built and delivered, so expect a detailed review in a couple of months.
