The Sentinel R-103 variant is identified by its slotted ejector and the forward-pull cylinder release integrated into the knurled ejector rod. This system works with the swing-out, fluted steel cylinder to provide straightforward loading and unloading.
Construction pairs an aluminum alloy frame and receiver with a steel barrel and cylinder. The 6 in. round, tapered barrel and full-size profile give this model a classic field-ready configuration in .22 LR.
Sights are fixed, with a ramped blade up front and a square-notch rear integral to the topstrap. Controls include an exposed, color case-hardened hammer for DA/SA operation.
Grip panels are brown checkered synthetic with a diamond motif, and the left side of the frame carries the Hi-Standard eagle medallion. This example was manufactured in Hamden, Connecticut, USA, and uses a largely screwless, pinned construction with coil springs.
