How do you fix a blown seal on a pellet rifle?

Answer 1

By buying a new gun it is not cost efficient to repair this type of gun

----------------- New answer----------------------------------------------

actually it is cost effective to purchase a new seal depending on what you spent on the air rifle. Many manufactures even send you a new C02 seal if that is what is bad. First try the manufacturer's home page and contact Customer service. If it's an older air rifle then do a search for "air gun repair" on the web and select someone near you to have it repaired. Or see the link below.
