TBH, I'm not sure. I don't want to give you bad intel. I don't have any first hand experience with the 28N spring, but it is clearly tagged for the Retaliator "expanded tube", whatever that means. Probably some sort of plunger tube upgrade for the Reta.

But I do have a box of K26 springs. The coil is WAY thicker than those 28N springs. So I'd be inclined to say the 28N is not a one-for-one replacement. But I dunno for sure.
