Because the Brigade Makasi platform features a bufferless, short-stroke gas piston operating system, maintaining peak performance requires factory-spec replacement parts designed specifically for this architecture. While many lower controls share standard AR-15 spring and pin dimensions, critical operating components—such as the Makasi Bolt Catch, internal guides, and gas system parts—require proprietary geometry for reliable lockup and cycling.

Using genuine Brigade Manufacturing OEM parts ensures proper tolerances, prevents premature wear on internal receiver walls, and guarantees smooth last-round hold-open function on both MK-15 (5.56 NATO) and MK-47 (7.62x39) setups.

Whether you are building out a spare parts kit for field maintenance or upgrading key control components on your Makasi pistol or rifle, all items in this section are 100% non-serialized parts that ship directly to your home with no FFL required.

All Makasi components are proudly designed, CNC-machined, and quality-tested at our facility in Miami, FL, backed by Brigade Manufacturing’s commitment to factory quality and customer support.
