The Upper Spring Cup 2-1/2in from HOWE is a precision-engineered bolt-on component designed for tactical rifle platforms and military-grade applications requiring reliable recoil management. Built for shooters and operators who demand consistent performance across high-round-count training sessions and duty cycles, this spring cup serves as the foundation for proper bolt carrier group function and buffer system optimization.
Constructed from cadmium-plated steel, the Upper Spring Cup 2-1/2in features a 1/8 inch threaded interface for secure bolt-on installation and accommodates 2.5-inch springs. The cadmium finish provides superior corrosion resistance and durability in harsh operational environments, preventing premature wear and maintaining dimensional integrity through extended service.
Operators and armorers benefit most from this component when maintaining or rebuilding AR-pattern rifles, where buffer system reliability directly impacts reliability and cycling performance. Installation is straightforward for anyone with basic armorer knowledge—simply thread on the component to secure it in place.
