    Finally got to break out my 300blk and put my new sdn6 on the end of it and have some suppressor joy. Was cleaning tonight and when separated the upper and lower looked like someone took a gold pepper shaker to the inside of the action.

    It might be normal but I have never seen anything like this. Of course cleaned then thought to take pictures......

    8.5 inch Noveske barrel, pistol length gas and std buffer weight. Shot supers and subs. Remington 220's and gemtech 187's. Never had this before the suppressor.

    Should I be concerned?

    Shooting the supersonic will over gas the system and increase the blow back into the upper and lower receiver. Do you have an adjustable gas block? I highly recommend you look into one. I have the MicroMOA and love it. It cuts down on blow back, recoil and dirt in the gun.

    It's from the Gemtec ammo. It is a filler to take up space in the casing for a more efficient and consistant powder burn.

    Noveske barrel and SDN6 here as well and I get the same thing when shooting Gemtech Subsonic ammo.

    Thank you everyone. The knowledge base here is awesome. Really appreciate it and great to hear it is the ammo and not something else.
