The KIDD Innovative Design BRN-22 Classic .22 LR slip-fit conversion receiver in Black (brand part no. KIDD-22RECVR-CLS-B) is a blowback-operated .22 Long Rifle upper receiver assembly that slips onto a standard AR-15 lower in place of a centerfire upper, converting the rifle to inexpensive rimfire ammunition for practice or plinking. Note that this is an upper receiver conversion unit, not a lower receiver, despite its listing here; it pairs with the builder’s existing AR-15 lower and trigger group. KIDD Innovative Design finishes this Classic model in a standard Black anodized finish to match most AR-15 builds. Among the AR-15 parts in the AR15 lowers category, this BRN-22 conversion unit is built for shooters who want low-cost rimfire practice on their existing AR-15 platform.
