The current MK2 Mod1 is really a MK2 Mod1.5. I have an original Mod1 (produced for maybe half a year), which has different receivers (SI-Defense billet vs Mod1.5 forged), came with a different buffer(CAR vs Mod1.5 PWS H2/H3), the MK216 version had a shorter rail (12" vs Mod1.5 15"), and didn't have an NP3 coated BCG or piston.
I will say that mine has had issues, but PWS' customer service has been among the best (I just got my rifle back last week with a new barrel).
