Again, trying hard not to beat the dead horse here, but the primary problem with prior posted results are that, as you know, they are not indicative of an accuracy break through that is in line with the overall claims about the innovations in your platform that can/will contribute to and provide improved accuracy. Specifically say improved accuracy over other rifles not having these same said breakthroughs/innovations.
Of course the posted results show that.
At one point, an off-the-shelf ammo was providing 2" groups.
After some adjustment it was tuned-in to less than 1" groups.
That in itself shows the capability of those features; go review the submitted groupings.
Moving forward, (and as it has been done plenty of times before) the operator will be able to find an ammo that groups close to 1" without adjustment, then move it down towards 1/2" with adjustment; and so-forth.
You cannot do this with other platforms except by changing recoil spring/buffer characteristics or by making handloads.
With the FD308, there is good-to-great accuracy potential with 147gr all the way up to 180gr; if you are willing to do the gas adjustments.
With the shorter 17"/18" barrel, this potential increases when adding a suppressor; which is what the original FD308 was specifically designed for.
With other rifles you are limited to a very narrow window of ability when it comes to getting the most out of what ammo you want to run.
If the ammo does not provide acceptable groups, then you move onto a different brand/load. With the FD308, you are less driven by that requirement because you have an alternative adjustment method.
Often this window becomes more narrow when adding a suppressor to a standard gas-gun. The opposite is true of the FD308.
The problem with simply handing a rifle like this off to someone who has no intention of performing the tuning, you cannot expect him to just sit down and get ideal groups, unless its by chance that the tuning is already proper for their body weight/posture, and ammo. With that said, the rifle was designed for technical shooters who demand adjustability under a wide variety of environmental conditions, wide variety of ammo usage, and variety or muzzle devices/suppressors.
As far as your usage of the term "breakthrough"; adjustability of the gas system is not a "breakthrough".
However, it is the first time an adjustable system has been used on a piston-op; which is where it happens to shine the most, due to its ability to influence "delay" issues associated with piston-ops.
Any "breakthrough" in accuracy would be attributed to the technical shooter (customer) who is able to patiently and successfully match up all the variables by using the adjustable system to their advantage.
We do it to a limited degree here at F&D, by proving the system works as its supposed to.
It's up to the end-user to take that to the next level if they are wanting competition-grade accuracy.
Now... in regards to a device that has not yet been introduced, I have full faith that it could be termed a "break-through", specifically in regards to piston platforms.
But since that feature is yet to be published, I will not go into further details at this time. For all pre-production customers, this feature will also be available for simple retrofit onto your existing rifles.
