Magpul UBR Gen2 Collapsible Stock OD Green AR-15/M16/M4

The Magpul UBR Gen2 Stock delivers enhanced stability and customization for AR-platform rifles through its unique dual-tube design and tool-free length of pull adjustment. This OD Green synthetic stock eliminates the wobble common in standard carbine stocks while providing shooters with precise fit adjustments.

What Makes This Different

Unlike traditional carbine stocks that slide on a single buffer tube, the UBR Gen2 utilizes dual guide rods and a proprietary buffer system for rock-solid lockup. The stock accepts standard AR buffer springs and weights while offering 1.6 inches of length of pull adjustment in 0.25-inch increments. This design provides the adjustability of a carbine stock with the stability of a fixed rifle stock.

Key Features

• Dual guide rod system eliminates stock wobble and play
• Tool-free length of pull adjustment from 12.6" to 14.2"
• Accepts standard carbine buffer tubes, springs, and weights
• Integrated sling attachment points for single and two-point slings

The UBR Gen2 excels in precision shooting applications where stock stability directly impacts accuracy. Competition shooters benefit from the consistent cheek weld and eliminated movement, while tactical users appreciate the quick adjustability for different gear configurations. The stock maintains its settings under recoil and rough handling, making it suitable for duty use and hunting applications.
