Magpul UBR GEN2 Collapsible Stock

The Magpul UBR GEN2 Stock combines the stability of a fixed stock with the flexibility of an adjustable carbine stock. Its rugged construction with integrated A5/SR25 receiver extension delivers a consistent cheek weld in every position and is ideal for demanding AR15 and AR10 platforms.

Consistent cheek weld with full adjustability

The stock offers eight positions including a fully collapsed setting while maintaining the same cheek weld throughout the adjustment range. This ensures a repeatable head position regardless of the selected length of pull.

Rugged construction for hard use

The reinforced multi-shell construction with dual locking system was engineered for heavy recoil, severe impacts, and intensive use. The integrated receiver extension further increases strength and durability.

Integrated storage and versatile sling mounting

A removable storage compartment provides space for batteries or small gear items. Multiple integrated QD sockets and sling loops support a wide range of carry configurations.
