The UBR GEN2 is an adjustable stock for the AR15/M4, designed to offer the same strength and stability as a fixed stock with a consistent and comfortable cheek weld in any position.

An update of the revolutionary Utility/Battle Rifle (UBR) stock, the UBR GEN2 features a fixed cheek piece to provide a consistent cheek weld in any of its eight positions and is compatible with Carbine as well as A5-length buffer systems. Designed to accommodate large bore AR calibers and withstand severe impacts, the UBR GEN2 is nearly five ounces lighter while retaining all the durability its predecessor was legendary for. Comes standard with front and rear QD sling attachment points, two footman’s loops, the ergonomic MOE SL™ angled-toe rubber butt-pad, and customizable storage compartment.

Made in U.S.A.


  • Mounts on a durable custom Receiver Extension tube (included) to accommodate the common M4 carbine buffer and spring as well as aftermarket A5 buffer systems*
  • Solid "fixed stock" lockup and consistent cheek weld in all positions
  • 8-Position LOP adjustability
  • Adjustment lever requires only gross motor movement to operate yet the entire stock remains streamlined and anti-snag
  • Enhanced lock mechanism with dual locking pawls for maximum drop strength and shock resistance
  • Multi-shell construction provides solid foundation and shields critical operating parts from penetration damage
  • Sloping cheek weld combines a slim profile with user comfort
  • Storage Compartment in tail of stock is removable and the door is reversible for user preference
  • Rubber butt-pad offers an anti-slip surface and increases impact protection
  • Rollover on the toe allows for easier shoulder transitions and better fit when using body armor
  • Sling Mounts
    • Front - QD swivel mount for ambidextrous one-point QD sling mounting
    • Left/Right Rear - Rotation-limited QD swivel sling mounts fit up to 1.5" push-button swivels
    • Bottom - 1.25" sling loop (additional loop accessible when Storage Compartment is removed)

Does this come with the buffer tube lock nut?
Kevin S on Mar 14, 2019
BEST ANSWER: Yes. Per the Magpul site all mounting hardware is included. The only thing you need to add are a buffer and buffer spring.
Can you change the buffer tube on the stock?

Definitely will be using this stock again on one of my builds.
Was slightly hesitant to spend the cash on this stock but I'm sure glad I did it's so worth the money. If you're looking to buy this stock but unsure of the price tag don't think twice it's so worth the price.

UBR Gen 2
When considering this stock; it was between the Gen1 or Gen 2. I did like the Gen 1 better and seemed more stable and less movement. I did like the price better on the Gen 2 and that is why I chose it.

Rock solid
Solid build quality, really easy install, and doesn't cut up me cheek like every other m4 stock. 5 stars from me.
