Maxim sells the CQB and SCW buffer/spring assemblies in standard, H1, H2, H3, and pistol-caliber versions, so the hardware exists to tune almost any configuration — the question is which one belongs in your build. In his buffer and spring breakdown on Greyhive, Brad from Maxim Defense answers the question the company gets most often: which buffer and spring do I need to use with which brace or stock? His short answer is to start with what the factory put in the gun, then adjust for variables one at a time. His longer answer covers the CQB Gen 6 and Gen 7 platforms, the shorter SCW system, the JP Rifles silent capture partnership, and the roller delay buffer built for 9mm PCC shooters. This guide pulls the specifics — weights in ounces, collapsed and extended lengths, charging force, and Brad's suppressor-specific recommendations — into one reference you can configure a build from. Key Takeaways Default to the buffer weight your factory build shipped with — an H1 gun gets a Maxim H1 for a direct swap. Add a standard suppressor and Brad recommends stepping up to an H3; a flow-through suppressor usually lands better at an H2. The CQB series is a mid-length system built around the CQB Gen 6 (stock or brace) and Gen …
