Grovtec Hollow Stock Pb Base

The GrovTec Hollow Stock Push Button Base (GTHM198) is a precision adapter designed for rifle stocks with hollow tube construction. This full-rotation push-button mount enables quick and secure attachment of accessories to hollow-core stock platforms, making it an essential component for shooters who demand modular, tool-free adjustability on the range or in the field.

Engineered by GrovTec, a manufacturer known for reliable mounting solutions in the rifle accessory market, this base features a compact 3 x 1 x 5.5-inch footprint and weighs only 0.06 lbs, ensuring minimal impact on overall gun balance. The full-rotation design allows 360-degree positioning flexibility, accommodating various attachment angles and user preferences without requiring stock replacement or permanent modification. The push-button mechanism provides positive engagement while maintaining the ability to detach and reposition accessories quickly, a critical feature for shooters transitioning between different shooting positions or swapping sling attachment points.

This adapter serves shooters who rely on hollow-stock rifle platforms—including AR-15 variants, modern sporting rifles, and other tactical builds with tube-style stocks. Competition shooters, hunters, and tactical trainees benefit from the tool-free repositioning capability when fine-tuning sling geometry or swapping between mounted accessories. The lightweight design and compact profile make it ideal for shooters who prioritize modularity and quick adjustments without adding significant weight or bulk to the rear of the rifle.
