IMPORTANT
To gain the full benefit regarding hammer spring pressure adjustment and fine tuning
you need to set the REGULATOR pressure to suit your own particular calibre of rifle .177 .22 etc
(On my particular Rifle it came out best at 92 bar in .22 calibre and fine tuned via the hammer to give a decent shot count)
Take care and
Be Lucky
