The Spikes Tactical ST22 Pistol Plug is a purpose-built lower receiver end cap for AR-15 style .22 LR pistol builds that do not require a traditional buffer tube. Machined from billet aluminum and finished in a durable black hard coat anodize, this compact plug threads directly into the rear of the lower receiver and provides a clean, snag-resistant termination point.

Designed around self-contained .22 LR bolt carrier and buffer assemblies, the ST22 Pistol Plug helps streamline dedicated rimfire AR pistols while adding a useful QD sling attachment point. Ideal for range use, training, and recreational shooting with lightweight .22 LR configurations, it keeps your build compact and simple. Spikes Tactical’s attention to detail and precise manufacturing deliver a plug that fits correctly, looks clean, and is built for long-term service.
