Who This Is For
The Magpul UBR Gen 2 is ideal for competitive shooters, tactical operators, and serious AR-15 enthusiasts who demand the stability of a fixed stock without giving up length-of-pull adjustability. It's equally at home on a duty rifle, a precision AR build, or a hard-use range carbine where a consistent cheek weld and rugged reliability are non-negotiable.

Frequently Asked Questions
What buffer systems is the Magpul UBR Gen 2 compatible with?
The UBR Gen 2 is engineered to work with Carbine-length, A5-length, and SR-25-length buffer systems, making it one of the most versatile adjustable stocks on the market. Whether you're running a standard mil-spec AR-15 or a larger AR-10/SR-25 platform, the UBR Gen 2 is designed to fit without requiring a dedicated proprietary buffer tube.
How does the UBR Gen 2 compare to a standard mil-spec adjustable stock?
Unlike a standard mil-spec collapsible stock, the UBR Gen 2 features a fixed cheek piece that maintains the same cheek weld height across all eight length-of-pull positions. This means your sight picture stays consistent whether the stock is fully collapsed or extended. The integrated buffer tube design also eliminates play and wobble common in traditional six-position stocks, giving you the rigidity of a fixed stock with the flexibility of an adjustable one.
Does the Magpul UBR Gen 2 include sling mounting options?
Yes. The UBR Gen 2 comes standard with both front and rear QD (quick-detach) sling attachment points, plus two footman's loops, giving you multiple sling configurations right out of the box. Whether you prefer a single-point, two-point, or three-point sling setup, the UBR Gen 2 has you covered without requiring any additional hardware.
