Prometheus 6.03mm EG Barrel 275.5mm HK416D Next Gen

The Prometheus 6.03mm EG Barrel 275.5mm HK416D Next Gen is a very high quality inner barrel manufactured from stainless steel.

This barrel has an overall length of 275.5mm and a diameter of 6.03mm, which puts it in the category of precision barrels. Because it is manufactured from stainless steel with a sublimely polished inner barrel, the very high quality is guaranteed. Besides being specifically suitable for the HK416D, this length also fits other replicas that have a length of around 275 mm.

Furthermore, with this barrel it is recommended to use a traditional bucking or Prometheus' own bucking as these fit best in the window of the barrel. We do not recommend using a Maple Leaf bucking with this barrel because the contact patch does not fit well through the window.
