HDR .68 40 joule barrel
Available now at Elite Shooter Supply, this precision steel barrel features a burnished protective coating for extreme wear resistance and ultra-smooth projectile passage. The extended barrel length allows the expanding CO2 gas to transfer maximum kinetic energy into your .68 caliber projectiles, delivering flatter trajectories, tighter groupings, and massive downrange impact force.
Designed with outer threading and a matching thread protector, this barrel easily accommodates tactical extensions, compensators, or mock suppressors. Upgrade your Umarex T4E HDR .68 with a direct drop-in tuning solution built for maximum power performance.
