Possible new eNMEy bolt engine?

Just to stir up some controversy:

This is the new bolt engine for the upcoming .50 cal eNMEy. It's designed so that there are no oring grooves in the firing can itself, so that maintenance is more like a Luxe. If you notice, the bolt is also more Luxe-like in terms of flow path. It's still an unbalanced spool but I dare say that if scaled up to .68 this system would outflow, and be more efficient than even my L6.

Rumor has it that a .68 cal version of this will become standard in the eNMEy and G1M but I can't confirm for sure. Also not certain if it will retrofit to current firing cans or not if that does happen. What do you guys think?

Any improvement on maintenance/efficiency would be awesome. I don't think it will be reverse compatible with the current eNMEy though. When you relocate o-rings from the firing can, you would be left with empty o-ring grooves which would definitely interfere with the new o-rings.

Interesting. Are they making an Extcy version with eyes?

That I couldn't tell you because I simply don't know. I've heard rumblings of a pretty big re-organization of their product line but I won't know anything specific until it's closer to being announced.

Changing directions in the flow like that is typically detrimental to efficiency - but significantly simpler to machine. If they transition the .68 caliber version of the gun to that style I wouldn't expect much if any better efficiency from it.

Having the ports perpendicular to the flow direction might just be a result of being for 50 cal. The breech section of the bolt is smaller, and therefore the "sail" section of the bolt is smaller. But it looks like they kept the section that goes through the bolt stop the same. Thus there is no space for angled ports.

To an extent I agree about the angle but taking into account the tiny ports in the stock bolt, I would lean toward this at least matching the L6's performance. Besides, with air following the path of least resistance I don't see it making a full 90 degree turn when it doesn't have a solid path to follow, like the inside of a 90 degree macro fitting or some Cocker bolts. Since the ports surround the circumference of the central bore, the path would be more of a "----\____" quick zig zag. Not ideal obviously but still resulting in higher flow from less resistance.
