Spring Cup 5.5in Short Swivel OD Alignment

The Spring Cup 5.5in Short Swivel OD Alignment by WEHRS MACHINE is a precision-engineered component designed for demanding tactical and military applications where rapid target acquisition and stable sight alignment are essential. This short swivel cup assembly serves as a critical interface between your optics mounting system and firearm receiver, delivering the repeatable accuracy that law enforcement and military personnel depend on in high-stress operations.

Manufactured to uncompromising tolerances, this component is built for operators who understand that equipment reliability directly impacts mission success and field safety. The 5.5-inch length provides a balanced sight radius that optimizes sight picture acquisition without adding excessive length to your weapon platform. The OD (Olive Drab) finish offers corrosion resistance and effective light-signature reduction in field conditions, while the swivel design accommodates traditional sling attachment points with minimal vibration transfer to your optics.

This alignment cup is ideal for AR-pattern rifles and is designed to maintain consistent alignment through thousands of rounds and repeated mounting cycles. Precision machining ensures zero-shift resistance under recoil, making it a reliable choice for operators. With a weight of 2.28 lbs, the component adds minimal weight while delivering maximum structural integrity.
