Inner Barrel Prometheus EG 6.03 Krytac SPR 416 mm

This Prometheus EG Krytac SPR inner barrel has machined with very small tolerances (+/- 0.01 mm) and a very precise finish to make sure (quality) BB’s will have a tight fit inside the barrel that has an inner diameter of 6.03 mm (outer diameter is 8.5 mm). This will result in a lower loss of pressure and a very consistent seal around the BB, making for better accuracy.

The Prometheus EG Krytac SPR inner barrel is made of rigid high quality stainless steel. It will be much harder to deform than an original barrel, meaning it can handle some rough use. We supply this barrel including two O-rings.
