Which are better/more durable? I had the Mil.Spec set on my old EVO IX MR, and I'm looking to upgrade the seals on the one I just picked up. I didn't know STM made these, so I'm just trying to get some feedback from anyone who's used them before I order.

 

We sell and install both. To be honest, They both seem to work about the same and last just as long.

aiight, thanks for the feedback. I'm ordering a set from you guys as we speak.
