Reply To: .25 Marauder Breach Seal Replacement
I’d run it until an issue comes up, naturally having a spare in the parts bag would be wise. Crosman does say to lube that o-ring every 500 shots, I’ve seen plenty of Air Arms with the same inside barrel o-ring last for many years. Never noticed any prob drag on the aa but the marauder does seem to drag on the o-ring a good bit with a mag or single and lubing it every 200 or so shots makes it feel better.
Get a ( some ) spares and don’t forget to lube them before placing in storage , really extends there shelf life.
