Spring Cup 5in Short Bolt-On OD Alignment

The Spring Cup 5in Short Bolt-On OD Alignment from WEHRS MACHINE is a precision accessory rail system designed for tactical carbines, precision rifles, and modular weapon platforms requiring dependable, repeatable optic mounting solutions. Built for shooters who demand zero-shift accuracy—law enforcement, military personnel, and competitive marksmen—this bolt-on alignment cup integrates with existing rail systems to provide a stable platform for optical devices, thermal imaging, or secondary aiming systems without requiring permanent modification to your firearm.

This 5-inch short model features a spring-loaded cup design that maintains precise geometric alignment under recoil and operational stress, critical for maintaining point-of-aim consistency across extended shooting sessions or rapid-fire engagement. The OD (Olive Drab) finish provides a non-reflective, mil-spec aesthetic that integrates seamlessly with combat optics setups while resisting corrosion in field environments. Weighing just 2.18 pounds, the compact 5.95 x 2.2 x 7.9-inch profile minimizes weight signature and sight offset, allowing for co-witnessed iron sights or backup aiming systems without interference. WEHRS MACHINE's engineering ensures positive, repeatable engagement through bolt-on installation—no gunsmithing required.

Operators working with AR-platform carbines, precision bolt-actions, or modular rail systems benefit most from this alignment cup's compatibility with standard Picatinny and M-LOK configurations. Installation is straightforward for users with basic mechanical aptitude—bolt-on mounting eliminates time-consuming permanent modifications. This component pairs effectively with 1-4x combat optics, LPVO (low-power variable optics), or red dot systems where secondary elevation or windage adjustment is necessary. Field-tested by tactical professionals, the Spring Cup 5in Short Bolt-On OD Alignment delivers the reliability and precision alignment that modern tactical and hunting applications demand.
