Integrated QD Socket – Built-In Sling Attachment
A standout feature of the SLA500P pistol buffer tube is the integrated QD (Quick Detach) sling socket located in the rear of the tube. This lets you attach a QD sling directly to the buffer tube, no extra end plates or adapters required. Classic Firearms+2RightToBear+2
Benefits of the rear QD socket:
Clean, minimalist single-point sling attachment point
Eliminates the need for separate QD plates or sling mounts at the rear of the receiver
Keeps your sling connection close to the centerline of the pistol for better control and transitions
For shooters who like to run a single-point sling on their AR pistol, this is a major convenience and a big reason to choose the Spike’s tube over generic options.
