It comes packaged in the Strike & Defend Upgrade Kit; it can be purchased separately through Amazon.
Its barrel is located directly above the stock attachment point, which makes it unusable when attached to most blasters. On low profile blasters, the Blaster Stock remains unblocked and it is still possible to fire it while attached. It features a single short tactical rail behind its barrel.
Reloading and firing
To reload the Blaster Stock, load a dart into the barrel; pull the plunger handle downwards to prime the blaster.
Pull the trigger to fire a dart.
