Now i see why you are so set on TC having a lifetime warranty, i was reading randy wakemans review of the winchester x-150 and he says it comes with a lifetime warranty. heres what i found on his website: The X-150 gets high marks for the excellent rubbery stock / palm swell / recoil pad and quick release bolt, good hunting accuracy, decent trigger, thoughtful ramrod, and easy-loading, but somewhat lower marks for its hard-to-cap breech plug, and skimpy manual. The X-150 features a lifetime warranty.

He forgot the word " limited" lifetime warranty. Says limited lifetime warranty in my manual. The reason they say limited is exactly what you said " try replacing that barrel in 20 years" The omega wont be here in 20 years. there for they will more than likely stop production of the barrels and other parts and thats where places like green mountain come in and start producing new barrels like they do for the old TC and some cva's. Thats why i got a new rifle from cva, they no longer make the cva blazer and have no replacement parts due to it being old and out of date, so they sent me a staghorn. Oh wait the omega is a god send, here if you dont believe me, Try getting replacement parts from tc for the tc patriot pistol.
