If you are going to quote people please get your facts right, there is a companies reputation at stake here.
My mod has fired between 200-250 rounds out of a 243, the mod had never been cleaned prior to the first pic being taken.
After cleaning the mod was mostly in good nick except for the small bit of gas cutting as seen in both pics.
I was at the time of purchase under the impression that the baffle stack was made from titanium, so yes the fact that is actually mostly alluminium is a disapointment to me.
I mostly share the opinion with Ronin that mods are consumable items and should be treated as such but also believe that the companies selling them should be honest about the components used and not give artificial impressions about the materials being superior to the reality.
I too have a DPT mod (and others) but the DPT has fired a similar amount of shots to the F&D in a similar time frame, these are all high velocity rounds out of a 20BR and it hasn't been cleaned either.

Make your own minds up but looks like its showing signs of gas cutting and muzzle blast on the first section to me.
The joy of this design is that I can just replace that section in the future at pretty low cost
