The Nordic Components 22RB Upper (brand part no. 22RB-UPPER-16-KIT) is a complete, dedicated .22 LR upper receiver built to convert a standard AR-pattern lower into a purpose-built rimfire rifle for recreational shooting, training, and small-game hunting. Its 16-inch barrel clears the federal rifle minimum, and the upper is manufactured using the same materials as a standard centerfire AR-15, so the completed rifle looks and handles like a full-size AR rather than a lightweight rimfire adapter. Feeding from 10-round magazines, it gives shooters an accurate, low-cost way to log trigger time and train fundamentals without burning through centerfire ammunition. Because it is a true dedicated .22 LR upper rather than a conversion block dropped into a centerfire bolt carrier, reliability and feel closely track a centerfire AR-15.
