The Gen 6 CQB Pistol System by Maxim Defense is your choice for simplicity and compactness for your AR-15 pistol. This system features a Gen 6 style housing, and CQB length buffer tube.

It is compatible with your standard bolt carrier group, but you will need our proprietary CQB buffer & springs or JP Silent Captured Spring if you don’t have one.

The CQB Pistol System is compatible with any MIL-SPEC lower receiver and it does not accept a stabilizing brace. For those that are looking to convert their existing CQB brace into the Pistol System, you only need the housing as your existing extension tube is compatible.
