Cobalt Kinetics PRO Series 9.8" Upper Receiver Group

Cobalt Kinetics supplies the PRO Series upper receiver group as an assembled unit, not a bare receiver and a bag of small parts. It fits a standard AR pattern lower on the usual takedown pins.

This is the 9.8" configuration in the PRO Series lineup. That figure is the designation Cobalt Kinetics uses to separate lengths within the family, and the distributor passes it through without saying what it measures, so it is reproduced here as the configuration length. Chambering is absent from the distributor record for this SKU, so verify the caliber marking on the receiver before you build around it.
