Worker Harrier Bearing Slide Sleeve

Priming on a stock Worker Harrier can feel gritty or stiff over repeated use, and the Bearing Slide Sleeve is Worker's fix for that — it's a direct upgrade part that smooths out the priming stroke so each cycle feels more consistent and less like you're fighting friction inside the receiver.

The set includes two kinds of bearings, plastic and metal, though it's worth flagging that newer batches of this part don't include the metal bearing — so if you're specifically after the metal version, check current stock before assuming it's included. Either bearing type still delivers the same smoother-priming benefit described above. This sleeve is built specifically for the Worker Harrier, so it's a direct fit for that blaster's priming mechanism rather than a universal part.
