Magpul UBR GEN 2 Adjustable StockThe Magpul UBR GEN2 Collapsible Stock is built for shooters who want the stability of a fixed stock with the flexibility of an adjustable design. It fits AR-15/M4 and AR-10/SR25 platforms and uses a custom included A5/SR25-length receiver extension to provide a consistent cheek weld, strong lockup, and eight total positions. The result is a stock that feels solid in use while still allowing quick length-of-pull changes for different shooting positions, body armor, or gear setups.Designed for hard-use rifles, the UBR GEN2 features a reinforced lock mechanism with dual locking pawls, a sloping cheek weld, a reversible storage compartment, and multiple sling attachment options. Magpul also includes the required custom receiver extension tube, buffer spacer, and mounting hardware with the stock, though a compatible carbine or A5 buffer and spring are still required for use.Features Eight total positions with fixed-stock style lockup Includes custom A5/SR25 receiver extension tube Consistent cheek weld through all positions Reversible, removable storage compartment Front and rear ambidextrous QD sling sockets Includes footman's loop, with a second loop accessible under the storage compartment MOE SL angled rubber butt-pad for grip and easier shoulder transitions Reinforced lock mechanism with dual locking pawls Made and engineered in the USASpecifications Model: MAG482 Platform Compatibility: AR10 / M110, AR15 / M4 Compatibility: Any small or large frame AR Length of Pull, Collapsed: Approx. 11.3 in.
