This is our CAR-15 SD 9 integrally suppressed ready uppers. It comes in 9mm only and is straight blowback. The ported barrel  is threaded 18x1 for HK MP5SD type suppressors and is designed for supersonic 9mm rounds. The ports bleed off gas, slowing the bullet to subsonic speeds so no subsonic ammo is required. The upper receiver is black anodized aluminum and our rail was designed to accept the HK MP5SD handguard which is included and has an ID of 1.8”. This is for the barreled upper only without sights,BCG or CH. Suppressor not included. These are built per order and running about 2-3 weeks ETA.
