Magpul UBR Gen2 Collapsible Stock Adjustable – Black for AR-15/M4 MAG482BLK

When the moment counts, precision can’t be compromised. You shoulder your rifle, settle behind the optic, and feel the solid, confident lockup that only one stock can deliver—the Magpul UBR GEN2 Collapsible Stock. Designed for shooters who demand strength, consistency, and adaptability, the UBR GEN2 bridges the gap between fixed and adjustable platforms. Whether you’re engaging at distance or maneuvering through close-quarters environments, this stock stays rock-steady under pressure.

The Magpul UBR GEN2 isn’t just an upgrade—it’s a redefinition of what a rifle stock can be. Every detail is built around performance. The fixed cheek piece remains stationary through all eight adjustment positions, giving you the same sight alignment and cheek weld no matter how you configure your rifle. It’s this unflinching consistency that separates the UBR GEN2 from the rest—whether you’re behind a precision AR-10 or a hard-running carbine.

Engineered from reinforced polymer and aluminum, the UBR GEN2 sheds nearly five ounces from the original design while retaining Magpul’s legendary toughness. Its proprietary receiver extension system accommodates multiple buffer setups, so you can tune your rifle exactly how you want it. From its dual locking pawls that prevent wobble to its customizable storage compartment and multiple sling points, every component is optimized for reliability and versatility.

For the precision shooter, it’s the ultimate foundation—rigid, balanced, and confidence-inspiring under recoil. For the operator, it’s built to survive the harshest conditions without compromise. For the rifle builder, it’s the one stock that truly does it all.
