Maxim Defense Industries Cqb Stock Standard Buffer & Spring Black

The Maxim Defense CQB Stock with Standard Buffer and Spring is a purpose-built AR-15 stock designed for shooters who prioritize compact handling without sacrificing adjustability. Unlike stocks that rely on buttons or levers, this system deploys with a simple pull—fast, intuitive, and reliable when it counts. Built for close-quarters work, home defense, and tactical carbines where space matters, the Maxim CQB stock collapses to just 5.35 inches over your receiver, making it one of the most compact options available for modern ARs.

The stock features four distinct positions that let you dial in length of pull for different shooting scenarios, body armor, or gear loadouts. Whether you're running it fully collapsed for tight spaces or extended to full carbine length, the adjustment system is straightforward and durable. Maxim Defense engineered this stock with real-world use in mind—no gimmicks, no complicated mechanisms, just solid functionality built to handle the abuse that matters.

This package includes Maxim Defense's Standard weight Tungsten Buffer and Spring, specifically tuned for the CQB stock's geometry and performance characteristics. The buffer and spring combo ensures reliable cycling and consistent feel across your chosen length-of-pull positions. If you're building a short-barreled rifle, upgrading a home-defense AR, or setting up a truck gun that needs to stay compact, this stock system delivers the versatility and durability expected from Maxim Defense.
