Magpul UBR GEN2 Collapsible Stock for AR15/M4 & AR10/SR25

The stock that refuses to compromise — the UBR GEN2 collapses like a carbine stock and shoots like a fixed one.

The Magpul UBR GEN2 (MAG482) — Utility/Battle Rifle — solves the collapsible stock's oldest flaw. Its cheek weld riser stays fixed relative to your face while the butt extends and retracts beneath it, so every length-of-pull setting delivers exactly the same head position and sight picture. Combined with a chassis engineered to near-zero play, the UBR gives hard-recoiling AR10/SR25 builds and duty AR15s a stock with genuine fixed-stock integrity.

Storage is built into the butt, the rubber pad plants firmly, and the structure tolerates abuse — buttstrokes included — that would destroy lighter designs. It is the heaviest-duty collapsible stock Magpul makes, and it feels like it.

Why shooters choose the UBR GEN2

• Constant cheek weld riser — identical head position at every length
• Near-zero play chassis — fixed-stock rigidity, collapsible convenience
• Fits AR15/M4 and AR10/SR25 — built for big-bore recoil
• Integral storage compartment — essentials sealed onboard
• Four finishes — Black, Flat Dark Earth, Olive Drab Green, Stealth Gray

Fit & installation

Supplied as a complete system with its own receiver extension — installs in place of your existing buffer tube assembly. Allow a little more bench time than a slide-on stock; the result justifies it.
