The Most Comprehensive Stock on the Market – Great Value for Your Money
The Magpul STR (Storage/Type Restricted) is a drop-in replacement buttstock for AR15/M16 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″ rubber butt-pad which provides positive shoulder purchase to prevent slippage even with body armor or modular gear.

I like the look. I like the feel. Not an exact fit for the Mil-Spec buffer tube from Spike’s Tactical. Got it to go on, but does not extend all the way. I have three settings instead of six. Other than that, it is an awesome product.
Very pleased with the stock on my AR, I run the same stock on another AR and could not be more please. The stock looks good but functions the way it was intended for. The shipment time was amazing. Good job! AT 3 Tactical.
Quality product, fast shipping, no complaints.
Shipped ridiculously fast. Very easy installation and fit perfectly on my VLTOR buffer tube. Magpul products are aways of good quality.
