Probably one of the most fun guns to shoot in my collection. This is a Quarter Circle 10 AR45 I built with my AAC Ti-rant 45 silencer on the end. Chambered in .45ACP, takes Glock mags, and has a bolt hold open feature. Light, easy to handle, and super quiet. That said, it is a pain in the ass to clean after about 500 suppressed rounds. So much carbon and crud everywhere!
