PRODUCT DETAILS
The UBR GEN2 is an adjustable stock for AR15/M4 and AR10/SR25 platforms, designed to offer similar 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 and SR-25 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 the USA.

THE BEST OF ADJUSTABLE, FIXED AND STORAGE STOCKS
Solid “fixed stock” lockup and consistent cheek weld in all positions. 7 adjustments plus fully collapsed for 8 total positions. Adjustment lever requires only gross motor movement to operate yet the entire stock remains streamlined and anti-snag
INTEGRATED A5/SR-25 LENGTH BUFFER TUBE
Mounts on a durable custom Receiver Extension tube (included) to accommodate carbine buffers and springs as well as aftermarket A5 buffer systems*


EXTRA STORAGE
Storage compartment in tail of stock is removable and the door is reversible for user preference
NON-SLIP ANGLED RUBBER BUTT-PAD
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

EFFICIENT CHEEK WELD
Sloping cheek weld combines a slim profile with user comfort
SLING POINT VARIETY
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)
RUGGED AND DEPENDABLE
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
Silver (verified owner) –
The UBR stock line has always been an absolute pig (heavy). this one no different.
However the Gen 2 is about 4-5 ounces lighter than the Gen 1 without sacrificing much quality or rigidity in my opinion. I use this stock on my DMR which is a super heavy gun but the consistent cheek weld is worth it to me.
I wouldn’t market this as the stock for everyone, it’s definitely a very niche very purpose driven design. But if you need those features then the Gen 2 is your jam. A nice thing about this stock is that it comes with it’s own A5 length buffer tube. QD swivel system, and eliminates the end plate. So it saves you a little cost there.
