Guarder precision inner barrel in polished brass, with a 6.02 mm bore and a length of 650 mm, for standard AEGs and specified by the manufacturer for the PSG-1. The tight bore, enlarged hop-up window and anti-turbulence muzzle end work together for a smoother, more consistent BB flight.

Performance

Compared with wider-bore barrels, the 6.02 mm bore leaves the BB less play and guides it more consistently, while the polished inner surface helps it travel smoothly. The anti-turbulence end steadies the BB as it exits, reducing the disturbances that push it off its trajectory.

Installation

The 650 mm length is the one specified for the PSG-1; on other AEGs, choose the barrel according to the replica's original inner barrel, or to the outer barrel fitted if it has been extended. To get the most out of its precision, pair it with a hop-up bucking in good condition.

In the field

On the PSG-1 and other long-barrelled precision replicas, it is the choice for the designated marksman role, in woodland and MilSim games, where shot consistency and effective range count.
