The Magpul UBR Gen2 Collapsible Stock is a highly adaptable, mission-ready rifle stock designed for AR15/M4 platforms. An evolution of the original UBR, this second-generation model is lighter and more modular while maintaining the same robust A5-length buffer tube system, offering consistent cheek weld and dependable lock-up in all positions.
Constructed from impact-resistant polymer over a forged aluminum frame, the UBR Gen2 is engineered to withstand serious abuse—whether you're running drills at the range or pushing gear hard in remote Australian terrain. Designed for professional end-users, the stock features a consistent cheek weld, adjustable length of pull, and multiple sling attachment options, including QD swivel sockets and integral loops.
Whether you’re building a DMR, competition rifle, or tough all-rounder, the UBR Gen2 offers unmatched strength, stability, and reliability in a collapsible platform.
