DM12 Eigenbolt install questions

(Title should read eigenring, not eigenbolt...cell phone mess up.)

I'm about to install the eigenring on one of my DM12s, but I'm a little hesitant because the included instructions are kind of vague.

Could anyone with the mod done to a DM12 post some pictures? Found a bunch from previous years but none of the 12.

And I want to make sure I have all the parts.

My kit included the can, delrin piece with o-ring, 3 o-rings. (In the manual there is mention of another boring to go on the threads of the back cap, but I'm not sure if that's supposed to be in the kit or not)

The can seems to have the stop close to center but it's offset a little, which side should face towards the top hat? Where does the delrin piece belong and which way should it face?

Correct use of the 3 supplied o-rings?

The can's internal stop is slightly off center...which direction should the stop go? Meaning, should the shorter length from edge to stop face towards the top hat or towards the back cap?

put your black ring behind the three rings like this^^^^

then slide the black sleeve over it. should be the wider end.

makes your gun more efficient (in a small nutshell).. you would have to search for the eigenring thread to get the exact science involved, as i cant explain it.

If the eigenring is like other tophat mods, it basically makes the volume in your dump chamber smaller. So you have to increase your HPR pressure to compensate, which gives you more kick in return for better efficiency.

Stop slightly closer to the front, you don't want the ring not riding closely on the tophat.

The Eigenring is not a tophat mod. It does take up a small volume, but that's not what makes the gun more efficient. The Eigenring slides back when the dump chamber is emptied and prevents excess air being vented out of the dump chamber.
