The crud all over the inside and magazine looks bad but it is only cosmetic. Burnsy's right, it doesn't affect accuracy to have a coat of burnt powder on the next round.
For cleaning I use a few generous sprays of WD40 to loosen-up all the carbon in the receiver and BCG. I lay a few old newspapers below as you spray and let it drip out, soaked up by the newspaper. Then wipe with a few disposable paper towels and - Voila! I agree, the amount of black crud coming out on the paper towels is a shocker but you get used to it, and it doesn't have to be brand-new-clean, just reliable clean. Like the old saying, 'It's only kinky the first time!'
It doesn't really take any longer than cleaning a non-suppressed AR, just uses a few more paper towels. The only thing is, for precision guns I like to leave the barrels dirty to retain the zero so have to watch that the degreaser doesn't go into the barrel. The only time I will clean everything and include the barrel in the cleaning is if it's an SBR or 100M subsonic gun like a 300BLK. Retaining a precise cold-bore marksman's zero is a non-issue in those types of guns.
When suppressed, the extra crud in your receiver and mag is coming back via the chamber, not the gas system. I know this being a left-hander. It comes back out the chamber from an over-pressured barrel and blasts out the ejection port into your face. Your gas system; DI or piston, regulated or unregulated, or even an adjustable carrier really has nothing to do with that. The choice of powder, the volume of the suppressor and diameter of the suppressor bore (e.g. using a 30cal suppressor on a 6.5, or a reflex suppressor with a generous blast chamber) will have more effect on the build-up of crud than the gas system.
An ultrasonic cleaner works better than a vibratory tumbler in cleaning suppressed cases and baffles. Bit more effort drying it all out so only use it occasionally and pop the primers out first. Normally I just set the vibratory tumbler for double the usual time and come back a few hours later.
Make sure you detach the suppressor from the gun after shooting. Don't store it attached is what I mean. All that carbon is hydroscopic so you don't want to encourage corrosion in the barrel.
