Air Gunner - - Essential Airgun Knowledge -

Bar­rel shrouds usu­ally act like si­lencers as the blast of air be­hind the pel­let ex­pands into the void and dis­si­pates the sound- en­ergy. As far as the bar­rel it­self goes, there’s no dif­fer­ence be­tween springer bar­rels and those fit­ted to PCPs, apart from what many be­lieve to be the re­quire­ment of bore­main­tainence. While most users of pre-charged pneu­mat­ics, es­pe­cially the FT and HFT com­pe­ti­tion devo­tees, be­lieve their bores need a reg­u­lar clean­ing reg­i­men, the ma­jor­ity of spring gun­ners pre­fer to keep such main­te­nance to an ab­so­lute min­i­mum, and for good rea­son.

When a PCP is shot, the blast of heated air meets the cold steel of the bar­rel, and, what­ever the facts of the mat­ter, it’s easy to see how any ul­tra-keen shooter would worry about con­den­sa­tion, fol­lowed by rust. Springers are re­puted to eject tiny par­ti­cles of lu­bri­cant into the bar­rel when they shoot, pro­vid­ing pro­tec­tion from th­ese con­cerns. Other opin­ions may dif­fer!
