Steyr LP (Pistol) -1/8" BSP Charging Adaptor. Sought after alternative fill adaptor for your Steyr LP (Pistol) PCP, which allows easy filling from a standard fill line setup or our QC03 quick coupler setup. Our units are now "Through Drilled" to allow for conventional bleeding of the charging system without the need to partly unscrew the reservoir whilst still under pressure. This helps to prevent premature wear of the reservoir threads and any subsequent damage from debris entering the gun.
