Maxim Defense CQB Gen6 4-Position Collapsible AR-15 Stock, Black Aluminum, 5.30"-10" OAL

The Maxim Defense CQB Gen6 4-Position Collapsible AR-15 Stock is built for shooters who need a compact, no-nonsense stock that adapts to tight spaces without complicated mechanisms. Unlike stocks that rely on buttons or levers, the CQB Gen6 deploys instantly with a simple pull—ideal for home defense, vehicle carbines, and tactical environments where speed matters. At its shortest, it adds just 5.30" to your AR-15's overall length; at full extension, it matches a standard M4 carbine stock. Four adjustable positions let you dial in the cheek weld and length of pull for different body armor, gear loadouts, or shooting scenarios.

Built from black aluminum, the CQB Gen6 is engineered for durability in real-world use without the weight penalty of heavier materials. The stock assembly ships complete with a proprietary buffer, buffer spring, and buffer tube—everything you need for installation. One important note: this is a proprietary system not compatible with standard AR-15 buffer tube components, so plan your build accordingly and verify compatibility before purchase if you're retrofitting an existing rifle.

Whether you're running a short-barreled rifle in a truck, setting up a home-defense AR, or building a specialized tactical carbine, the CQB Gen6 prioritizes function over complexity. Four solid positions beat infinite adjustments if they're finicky, and a pull-to-collapse design means one less thing to think about when you need the gun to work.
