Maxim Defense SCW STD 3.3 oz. - Buffer and Spring

Start with the standard and tune from there. The Maxim Defense SCW STD Buffer and Spring gives you a 3.3 oz. baseline buffer weight that provides reliable cycling across a wide range of AR-15 configurations, making it the go-to starting point for most builds.

The Maxim Defense SCW STD Buffer and Spring is a 3.3 oz. standard-weight buffer and spring assembly designed to enhance Maxim Defense SCW stock and pistol brace systems on the AR-15 platform.

At 3.3 oz., the STD weight mirrors a standard carbine buffer, delivering predictable bolt carrier timing that works well with most factory gas systems and barrel lengths. This makes it the right first choice when setting up a new build or replacing a worn buffer and spring. The matched spring is tuned to complement the buffer weight for consistent feeding, extraction, and ejection cycle after cycle.
