The MP5 SD At Home (But Better)
This video explores the Broad River Tactical CAR-15 SD upper, a 9mm integrally suppressed system mimicking the MP5 SD on an AR-15 platform. It utilizes a CMMG radial delay bolt and a ported barrel to slow supersonic ammo to subsonic speeds. The build features a Replicator Ventus 9 suppressor and Mean Arms EndoMag kits for aesthetic magazine conversion. The CAR-15 SD offers softer recoil than competitors like the CZ Scorpion and POF MP5, but requires frequent cleaning due to carbon fouling.
