Magpul STR Carbine Stock
The Magpul STR (Storage/Type Restricted) is a drop-in replacement buttstock for AR-15/M4 carbines using mil-spec sized receiver extension tubes. A storage-capable version of the CTR, the STR has improved cheek weld and two water resistant battery tubes on a compact, reinforced polymer A-frame design.
A shielded operation lever and supplemental friction locking system prevent accidental operation and minimize excessive stock movement for enhanced weapon stability and accuracy. The STR incorporates two integral sling loops, a reversible push-button QD sling mount, and a replaceable 0.30″ thick rubber butt-pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.
Made in U.S.A.

Always loved Magpul
The stock was a little difficult to get on with the supplied dummy round, a flat screwdriver worked better for me. I love the cheek weld of this stock, I was a little worried about the seam/crack between the storage compartment and top of the stock would pinch or catch beard hair, but I have had no issues. The friction lock is a nice touch for precision shooters or perfectionists like me. All around a very nice stock for the price.
