My question is since this is my first SCAR, why the heck is there so much lost pressure and powder burns all over the front sight, and the front of the rifle? I mean in slow motion videos the flash that is coming out of the gas regulator switch is as bright as the end of the muzzle break or compensator. Why?? I don't see that happen on any other rifles I own like this one. It doesn't happen with my ACR .556 or with it's 300 Blackout bbl. Has anyone else seen the front of there rifle turning red with powder residue? It's a pain in the @$$ to have to take the forend extension off each time and clean this thing. I like my firearms clean as new and ready to go. I'm hoping this is not a normal issue with SCAR 17's. Thanks for your help and feedback!!!!
