6.20mm Delta Strike Barrel 509mm

The Prometheus 6.20 mm Delta Strike Widebore inner barrel offers BBs great stability with its 3-point retention insert and extended hop-up window. The 3-point retention insert centres the BB in the middle of the bore, while the extended hop-up window provides even better backspin, effectively increasing the range. The 6.20 mm wide inner bore ensures that air is cushioned under the BB as it slides along the top. This prevents the BB from hitting the sides of the inner barrel and provides a much smoother trajectory than OEM barrels. The air cushion significantly increases range and accuracy. The barrel is made from high quality heavy brass that has been finely polished and crowned for consistent performance. Internally, the barrel has been coated with what Prometheus calls the "BC Bright Coating", which provides an even smoother internal polish.
