High marks for this mod done by TheMeta666 in integrating the AceTech Blaster internals to the G&G MG42 muzzle brake. It would be great to watch this in action especially during night airsoft games with both features, tracer and muzzle flash generator activated... "Internals from the AceTech Blaster Tracer Unit are integrated in the Muzzle Brake from this MG42 Airsoft gun...

I think it works great!"
