CMMG
The CMMG AR-15 carbine buffer assembly is engineered for shooters running the most common gas-system configuration in modern AR builds. If your rifle uses a carbine-length gas tube—whether it's a factory M4-style setup or a purpose-built carbine platform—this buffer is matched to that system's cycling characteristics. Pair it with a compatible carbine-length spring and you get a complete receiver extension package that handles the specific impulse and dwell time of a carbine-length gas system, translating to reliable operation across a range of ammunition and shooting conditions.
CMMG's reputation in the AR market rests on attention to core functionality, and this buffer assembly reflects that philosophy. Rather than chase exotic features, it does what it's designed to do: work with your carbine-length platform without guesswork. Whether you're building a new rifle, upgrading a used lower, or replacing worn parts in an established carbine, this assembly fits the bill for shooters who want a proven, straightforward solution.
Installation pairs with any compatible carbine-length spring for a complete system. If you're new to AR assembly or maintenance, remember that buffer weight and spring rate must work together; CMMG's carbine-length designation ensures you're in the right ballpark for a standard-length gas system.
A carbine-length buffer assembly is designed specifically for AR-15 rifles with carbine-length gas systems, the configuration found on military M4 carbines and most modern commercial carbine builds. The carbine buffer is engineered to manage the cycling impulse of a shorter gas tube, which produces different pressure and timing than mid-length or rifle-length systems. Using the correct buffer length and weight for your gas system ensures reliable feeding, ejection, and bolt carrier velocity.
This buffer assembly requires a compatible carbine-length spring to function. Together, the buffer and spring form the complete receiver extension system that interfaces with your bolt carrier group and lower receiver.
This CMMG carbine buffer assembly is designed for AR-15 platform rifles using carbine-length gas systems. Compatibility depends on whether your rifle's gas tube is carbine-length. If you're unsure which system your rifle runs, check your rifle's manual or consult a gunsmith or retailer before purchasing.
