Question MK11 vs MK11 EVO

[suricatasuricata]

I bought a couple of what I'd hope to be identical MK11 Evos from abroad. Turns out I was shipped one MK11 and one MK11 Evo. Anyone know what the difference between the two should be? To my surprise, the MK11 is 497 grams while the MK11 Evo is 530 grams.

The difference of te MK11 EVO to MK11 seems to be the type of brass, two springs instead of one, four instead of two high flow LP Ports, the heat exchanger rips and the price......
