The Magpul UBR GEN2 Collapsible Stock is a heavy-use adjustable stock for AR-15/M4 and AR-10/SR25 platforms. It combines length-of-pull adjustability with a consistent cheek weld and fixed-stock lockup in all eight positions. A custom A5/SR25-length receiver extension is included and supports carbine buffers and springs as well as aftermarket A5 buffer systems. Dual locking pawls and multi-shell construction are designed to handle hard recoil and severe impacts. A reversible, removable storage compartment holds batteries or small gear, while front and rear ambidextrous QD sockets plus footman's loops support one- and two-point slings. The MOE SL angled-toe rubber butt-pad adds anti-slip contact and a rollover toe for easier shoulder transitions and better fit with body armor. Made in the USA.
