Magpul UBR GEN2 Stock with Buffer Tube for AR-10/AR-15 (Black)

Magpul UBR GEN2 is an adjustable stock designed for AR-15/M4 and AR-10/SR-25 platforms, combining the strength of a fixed stock with the versatility of an adjustable system. The updated Utility / Battle Rifle (UBR) version retains the legendary reliability of its predecessor but is 140 grams lighter while maintaining high structural strength. The stock features an integrated buffer tube and is specifically designed for large-caliber AR rifles, capable of withstanding significant loads and impacts during active use.

The UBR GEN2 has a fixed cheek rest that provides consistent and comfortable cheek weld in any of its eight adjustment positions. The stock is compatible with Carbine, A5, and SR-25 length buffer systems, making it a versatile solution for various rifle configurations. Standard features include front and rear QD sling swivel sockets, two sling loops, an ergonomic MOE SL® rubber butt-pad, and a storage compartment for small essentials.
