Re: suppressing AR`S and cleaning them

Pretty much everyone has the same reaction as you the first time that they shoot an AR pattern rifle suppressed.
The reality is that the majority of the fouling that is creating issues while shooting suppressed is coming from the bore, not the gas tube.
All the GP system will do is keep the BCG a bit cleaner and degrade accuracy.
GP vs. DI argument is pretty old, but the consensus agrees on at least these points:
- GP overall is a cleaner running platform.
- GP increases reliability if you don't take into account setting up a DI for high reliability.
- GP does not have near the parts availability or standardization of DI.
- GP is inherently less accurate due to the additional reciprocating mass in a separate plane than the barrel and additional pressures exerted on the barrel assembly.
(The accuracy claim is old and if you have any doubt, ask George Gardner of GA Precision or Jered Joplin on American Precision Arms.)

*BOTTOM LINE*
Gas Piston is perfect for people that like to have a clean gun but don't like spending two hours to get there.
All bets are off though when you add a suppressor.
The two solutions that I have seen work the best is a "Switch Block" type setup and / or appropriate rifle setup.
What is appropriate rifle setup?
I would consider appropriate rifle setup as keeping the BCG and locking lugs well lubricated in a quality product like Mobil-1 or SLIP 2000 EWL.
It is also appropriate to use a heavy buffer and spring to slow down the action.
(This allows more dwell time for gas to escape the bore / chamber.)
Start with the cheap solutions and work your way up:
- Oil is cheap, use it...
- Buffers are not too expensive and they are easily swapped in seconds.
- A Noveske Switch Block or other comparable products are pricey, but they are purpose built for what you are trying to do.
Remember "Step One" though...
