The Cobalt Kinetics CK-Pro Stripped Upper Receiver Group in black Cerakote (Cobalt Kinetics part no. CKPROURG13SBLK) is an AR15-platform upper receiver designed for end users who want to upgrade their current rifles to the same performance edge featured in Cobalt Kinetics’ completed platforms. As a stripped receiver, it ships without a barrel, bolt carrier group, or handguard, so builders can install their own components to spec. Every CK-Pro receiver is machined from aluminum and finished in a durable black Cerakote coating, then built to mil-spec tolerances for compatibility with standard AR15 lower receivers.
