Springer Modification Thoughts

... ldc means lead dust collector.....while they do collect some grey residue from pellets , they make your airgun near silent - but we use synonyms like : ldc , pickle , can , noise device , etc . silencers arent really a word we use - i guess to avoid unnecessary attention. laws on real devices have laxed lately, and it's largely for airguns, anyway - but that's my take on all of that. a real fiream would blow our airgun devices apart. - paul.
 
(De)compression of air in a fraction of a second gets hot, really hot! Up to burning levels on non fire resistant materials. I wouldn't use anything else than tried and tested piston heads. You'd risk damaging the seals. One of those HW seals work best to soften things up, guide rods and other parts made out of delrin also helps.
