it has 2 o-rings on the front and its the same shape as my stock etek bolt at the back and if it is home made it looks like theyve done a real job at doing itCure is shaped at the back
stock 06 has no Orings on the front nor does the nexus.
Has it got 2 Orings on the front? Bit hard to tell from the pic
If so I think someone has had an attempt to make a cure out of an 05 by adding Orings to the front.
Sure Nicky will tell you for definate
