I was interested as well to see the Effect appear after my project. I think it's a lot like what I set out to change by zbk110 to be. It the timing was a bit different, I might not have done what I did, but I tend to think I still would as it wasn't so much of the rifle that I was interested in, but the project. If you're intereted in a better looking/performing rifle, I'd pay close attention to what those people with Effect experinece have to say. Even though I have no experience with the newer rifle, it seems that there are some up front differences: the monoblock on the Effect seems to be larger in outer diameter and thickness as well as longer. Following that, the breach block looks to be wider, with a correspondingly larger contact area. These initial differences may go a long way towards describing diffent upper limits of proofing.

By the way, what do you want to end up with?
