Hi All,
I'm Darren Toms the owner of DPT suppressors in new Zealand.
Its a funny thing with suppressors that can be dissembled (and probably a down side of them), some people do freak out with the first sign of wear.
The wear on the baffles does look normal.
See bellow a little snippet from our instructions that are supplied with each suppressor we sell.
"
After the first 20 or so rounds you may find pitting on the module closest to the muzzle , that is nothing to be concerned about as its the anodizing wearing off, after the initial pitting you will find it wont change much the next few hundred rounds, life expectancy of that module is around 2000 rounds on a 22 inch hunting rifle. To prolong the life of the modules, when cleaning don't clean the carbon off the front face of the modules as it protects it. Life expectancy of the suppressor can be improved by not getting it too hot, a good rule of thumb is an average of 60 rounds an hour and 30 rounds an hour with a protective sleeve on the suppressor (because it slows the heat dispersion).If stainless steel blast baffle is used the round count goes up to 90 rounds per hour without sleeve and 45 rounds per hour with sleeve."
I hope that puts your mind at rest.
Darren
