The Magpul UBR Gen2 Stock delivers precision adjustability and enhanced stability for serious AR-15 platform users. This collapsible stock system addresses the common issues of cheek weld consistency and length-of-pull adjustment found in standard carbine stocks.
What Makes This Different
Unlike traditional carbine stocks, the UBR Gen2 features an integrated cheek riser and A2-length buffer system compatibility. The dual adjustment mechanism provides both length-of-pull and cheek height customization in 0.25-inch increments. This stock maintains consistent lockup across all positions, eliminating the wobble associated with mil-spec carbine tubes.
Key Features
- Dual adjustment system with length-of-pull range from 10.75" to 14.75"
- Integrated adjustable cheek riser with 0.25" increment positions
- Compatible with A2, A1, and rifle-length buffer systems
- Stealth Gray finish matches Magpul polymer accessories
- QD sling swivel socket and conventional sling loop included

The UBR Gen2 excels in precision shooting applications where consistent cheek weld matters most. Competition shooters benefit from the repeatable positioning, while tactical users appreciate the quick adjustment capability. The stock maintains zero shift during position changes and withstands temperature extremes from -40°F to 180°F. Installation requires no permanent modifications to the rifle.
