Spike's St22 Pistol Plug

The Spike's ST22 Pistol Plug is a precision-engineered chamber plug designed to secure and protect AR-platform firearms when unloaded, in storage, or during transport. Built by Spike's Tactical—a manufacturer known for exacting tolerances and field-proven reliability—this plug delivers the durability and tight fit that firearms operators depend on for safe, organized armory management.

Measuring 3 × 1 × 3 inches and weighing just 0.06 lbs, the ST22 Pistol Plug is compact enough to fit into field kits, spare parts bags, or range bags without bulk. The precise manufacturing Spike's is known for ensures a snug fit that prevents accidental chamber obstruction during storage or transport. The durable construction resists corrosion and wear from repeated insertion and removal, maintaining its function across extended service intervals. This is the type of consumable-level component that serious shooters and armory custodians stock in multiples to cover each firearm in their rotation.

Buyers seeking pistol plugs for AR-9 or similar .380 ACP-platform builds, range officers managing multiple cleared weapons, and firearms owners maintaining safe unloaded storage will appreciate the reliability and build quality of this Spike's component. It eliminates guesswork and potential chamber debris contamination—a real concern in high-volume training environments or long-term storage scenarios.

As a standalone accessory, the ST22 Pistol Plug represents the kind of small-scale, high-reliability part that defines Spike's market position: not fancy or flashy, but engineered to spec and trusted to work when it matters. The long-term reliability and excellent build quality ensure years of service without degradation or fitment drift—critical in applications where chamber security is non-negotiable.
