Marker Feedneck Interfaces

The feedneck is the structural interface that connects the loader’s outlet to the marker’s breech. Its primary functions are to hold the loader in a consistent position and to provide a conduit for paintballs to move into the feed stack. Most feednecks use clamping mechanisms or collars that can tighten around a loader’s outlet tube, balancing retention strength with the ability to remove or adjust the loader when needed.

Internal dimensions of the feedneck are chosen to accommodate nominal paintball sizes while preserving enough clearance for smooth movement. The length and shape of the neck influence how compression loads from force feed systems are transmitted to the marker body and how friction is distributed along the stack. Smooth internal surfaces and gradual transitions between loader outlet, feedneck, and breech help reduce opportunities for paint to catch or wedge.

Standardized or widely adopted outlet diameters allow loaders from different manufacturers to interface with a broad range of markers. Feedneck designs vary between fixed height, low rise, and adjustable rise formats, each with different implications for marker profile and loader balance. In technical descriptions, these features are grouped under feedneck interfaces because they define the mechanical boundary where loader and marker systems meet.
