Compatibility - All matrices DM and PM up to 08 model year (Not Rail and SLG). All PMs without internal milling. DM9 through DM11 version is here and awaiting o-rings to be added to the site.
Q:Is this just Lurker's version of a "Top Hat mod"?
A: No! The Eigenring moves along the length of the top hat, so the benefits of a low pressure and high efficiency are realized. The size of the dump chamber changes during the shot, resultsing in the most efficient use of air possible.

Q: Does the Eigenring use a spring?
A: No. The Eigenring works on airflow restriction to dynamically create a pressure difference to drive it's motion. While early versions utilized a spring, we discovered it was more efficient to forego it and simply space the ring out with the 3 included o-rings.

Q: Does this change my bolt position?
A: Due to the thin spacer provided, the bolt tip does move very minorly forward in the breech. In most cases this is a positive change resulting in less rollback and gentler operation. However, if any issues are identified with the install relating to bolt position, simply add an o-ring around the outer diameter behind the large threads on the back cap. This will prevent the engine from moving too far forward. Additionally, check the bumper sail o-rings, as the bolt may progress too far if they are worn or the LPR is at a high setting.

Q: Are these compatible with polished/TechT/Billy Wing bolts?
A: Billy wing and polished stock bolts will work synergistically with the Eigenring due to their ability to lower dwell from the decreased friction. I recommend a polished stock bolt for cost efficiency. Techt bolts with the top hat cut outs will not work, but the ones with a smooth top hat will.
Just wondering? In step two under the section of Tuning for your ring, it says to turn out your LPR until gun cycles "inconsistently". Is that a typo? Should it be "consistently". Just wondering, thanks.
Hey Lurker, I was just wondering. When you turn out the LPR on the DM, you would be increasing your pressure to the LPR, therefor your consistency should increase not decrease as stated in your guide. Should it be written that your LPR be turned in until inconsistency develops,not out like it is currently written? I hope my confusion is explained to your understanding, I don't want to bother you and if I am mistaken, sorry in advance. really looking forward to your DM9 ring. Not sure if you remember me, but I have been patiently waiting from the very beginning. I knew you would be able to figure something out, you are a great engineer, thanks for your time.
So to take advantage of the ring is it crucial to use the lowest dwell possible? I was tuning it earlier according to your directions but I prefer the way my DM7 shot on 21ms, will I still have gains in efficiency over stock?
I was wondering the same thing. I LOVE how my PM7 shoots with longish dwell, it's so quiet, smooth, efficient and gentle on paint I'm not inclined to reduce my dwell.
Can anyone speak from experience? I'd imagine that to some degree we would see the same benefit due to the reduced dump chamber volume and the concept behind the ring (maintaining dump chamber pressure longer as it empties) but I'm curious to what degree.
