Airsoft EmBro presents a detailed build of an MP5SD5, starting with a CM.041 SD6 as the base gun. The video guides viewers through the process of upgrading the gun, including the wiring and stock, adding a suppressor cover, and installing a Picatinny rail on the handguard. Further enhancements cover the top rail, a flashlight with a mount and hot button, and finally, a foregrip, magwell, and red dot sight with a killflash.

The final build features several key components. The upgrades include an A2 fixed stock and a Multicam Black suppressor cover. The build also uses a Midwest Industries top rail and a Modlite PLHv2 with a UE Scout Light Rear Cap. It's equipped with an ARISAKA Defense Offset Scout Mount, a UNITY Tactical Hot Button, and a Magpul MOE RVG foregrip. For the flared magwell, the builder chose a Haga Defense, and the optic is an Aimpoint CompM4 red dot with a killflash.
