Rocketkey HDX 68 | PS-320 and HDS 68 | PS-300 - 40 joules tuning valve

The Rocketkey export valve made of hard-anodized, high-strength material (A7075) increases the performance of the Umarex HDX 68 T4E and PS-320 shotgun from the factory-set 7.5 or 16.0 joules to a powerful 40 joules .

The Rocketkey export valve is also suitable for the HDS68 or PS-300 . After installation, the output of these two shotguns is a powerful 20 joules .

The Rocketkey.68 valve pin is slightly shorter than the original part and has an optimized tip geometry, which results in a longer valve opening time and thus higher performance.

A Co2 capsule is enough with this tuning kit for about 15 shots .

• Rocketkey 40 Joule tuning valve suitable for the HDX 68 and PS-320 shotgun as well as the HDS 68 and PS-300 shotgun
