sm50 is fine dont have a break down of what it contains but its not just silicon its a mix ,i used it for years on seals but now i coat with anti scuff like gn paste ,then wet with dryslide type lube ,both high molly content this way every time you cock & fire your rifle it buffs itself in no need to put dryslide in compression tubeOriginally Posted by T 20
The top tuners from the past used to recommend the use Silicon oil on piston heads in the form of SM50.
As you advise against the use of Silicon, I thought I'd ask what you recommended instead ?
All the best Mick
i can send you a sample of my moly lube (dryslide) but much thicker no charge if you pm me your addy
thanks dave
