Inner Barrel Prometheus EG 6.03 Next Gen HK416D 275.4 mm

Do you want to replace the standard inner barrel of your replica? The Prometheus EG Next Gen HK416D inner barrel takes on that role and boosts your performance. You gain considerable accuracy because the air seal is optimal and, most importantly, because the hop-up works really well with a high-quality barrel. Combine it with good BBs and you'll get the most out of it — for the dedicated player, a logical upgrade.

The material plays a major role in this. Stainless steel is rigid and bends barely, which means this barrel withstands impact better than the original. Moreover, stainless steel expands less than brass or aluminium, the materials most inner barrels are made of. If you fire a large number of BBs in succession and the barrel gets warmer, you'll notice hardly any loss of accuracy.

Besides the material, the difference lies in the precision of the manufacturing. With an inner diameter of 6.03 mm, Prometheus maintains a margin of only +/- 0.01 mm. The outer diameter is 8.5 mm and the finish is of high quality. At the end, the barrel flares out slightly; this prevents an abrupt pressure drop at the muzzle from causing instability and ensures the pressure drop is gradual.
